Machinery is a combination of objects, assuming the force added to the deformation of its parts is difficult. 2. These objects have with each other, the single, the provisions of the movement. 3. To put the energy into the most useful form, or into effective mechanical work. The concept of mechanical Chinese Concept "Mechanical" words from "machine" and "mechanical" components of two characters. "Machine" - originally referred to the local key parts; "armed" - the original in ancient China refers to a whole device or apparatus. The two words together to form the "mechanical" word, they constitute a general mechanical concept. "Mechanical" in ancient China refers to the equipment, utensils and other in-kind. "Zhuangzi World" contains "a mechanical here, hundred Baptist day patch, and see the work force more than a very few", the "armed" in this for the general equipment or apparatus; "Mozi Public input": "public input as to Chu made the mechanical ladder "in this refers to the weapon;" Han Qian Biography "contains:" Huaiyin (Han), the king, by the armed Chen "in the" mechanical "means the instruments of torture. Western concept In general, the mechanical difficulty of the work is help people to reduce the labor-saving tools or devices, such as chopsticks, broom and tweezers, a class of objects can be called the machinery, they are simple machines. And complicated machinery is composed of two or more kinds of simple machines pose. We usually call these relatively complex mechanical machines (the next volume of the fifth grade science textbook.)

Machinery - the definition of mechanical
Institutions and the definition of the machine from mechanical engineering, is the most basic principles of modern mechanical concept of the modern Chinese concept of multi-machine from the Japanese of the "mechanical" in the Japanese concept of mechanical engineering to make the following mechanical definition ( that meet the following three features as mechanical machine): Is a combination of mechanical objects, assumes power added to the deformation of its parts is difficult. These objects have with each other, the single, the provisions of the movement. To exert the most energy into useful form, or into effective mechanical work. Has determined the movement of all machine systems and institutions in general. Such as tractors and other machines; rigid; not flexible. Mechanical Engineering is to science and technology-related natural science theory, combined with the production of technical experience gained in practice, research and resolve design, manufacture, installation, use and repair of various mechanical problems in a theoretical and practical an applied discipline. The development of various engineering fields require mechanical engineering corresponding development of mechanical engineering are required to provide the necessary machinery. Some mechanical invention and improvement projects will lead to new technologies and the emergence of new industry and development. For example, successful large-scale manufacture of power machinery, led to the establishment of the power system; locomotive railway engineering and invention led to the rise of the railway undertakings; internal combustion engines, gas turbines, rocket engines and other inventions and progress, and aircraft and spacecraft led to the successful development of aviation, the rise of the aerospace industry; the development of high-voltage equipment, new synthetic chemistry led to a number of successful projects and so on. Mechanical Engineering is to continuously improve all aspects of the demand for access to development under the pressure of power, and from all disciplines and at the same time technological advances in improved and innovation. 1 The usual explanation: Machine is a simple device, capable of energy, power passed from one place to another. It can change an object's shape and structure to create a new object. In life around us there are countless different types of machinery in the work for us. Machinery, mechanical devices everyday understanding, that is, all kinds of machinery and equipment. 2. Explained the importance of: From a professional point of view, machinery: mechanical basis of a very important position. Machinery of modern society the five elements of production and services (that is, people, capital, energy, materials and mechanical) one.

Mechanical - Mechanical Engineering Development
Humans as "modern" logo is to create tools. Variety of the Stone Age axes, stone hammers and wood, leather tool is a simple rough pioneer subsequently the machinery. Evolution of simple tools from manufacturing to manufacturing by a number of parts, components of modern machinery, experienced a long process. Thousands of years ago, mankind has created for grain shelling and grinding and crushing of the mortar used to provide water, Jie Gao and pulley, the car wheels, navigation in the river and paddle boats, oars, rudder and so on. Power used, from people's own strength, to the use of animal power development, hydro and wind. The materials from natural stone, wood, earth, leather, the development of synthetic materials. The earliest man-made materials are ceramics, pottery ceramics manufacturing cars is a power, transmission and work of three parts of the complete machinery. Mankind from the Stone Age into the Bronze Age to the Iron Age and then again to blow the fire blower Wang played an important role in the development. The blower is strong enough, to make metallurgical furnace to obtain a high enough temperature to get the metal from ore smelting. In China, 900 years before 1000 BC have been smelting with the blower, and gradually developed from human to animal power and water blast blast. 15 to 16 centuries ago, the slow development of mechanical engineering. However, in the millennia of practice, in the mechanical development or accumulated considerable experience and technical knowledge, became the major potential for the development of mechanical engineering. After the 17th century, capitalism in Britain, France and Western Europe appear, commodity production became the central issue of society. The late 18th century, the application of steam from the mining industry to promote the textile, flour, and metallurgical industries. The main material production machinery to switch gradually from the timber is more tough, but it is difficult with the manual processing of metals. Machinery manufacturing industry began to take shape, and in the decades become an important industry. Mechanical engineering by the growing practice, from dispersion, rely mainly on their individual talents and skills craftsmen of a technique, has gradually developed into a theoretical guidance, systematic and independent engineering. Mechanical Engineering is to achieve 18 to the 19th century industrial revolution, and the machinery of capitalism the main technical factors mass production. Power is an important factor in the development of production. The late 17th century, with the improvement and development of machinery, coal and metal ores with the requirements of the annual increase, people are not relying on the production of human and animal power to a new stage. In the UK, textiles, milling and other industries will be more and more factories in the river, using water wheels to drive the working machinery. But the then coal, tin, copper and other mines in the ground, still a large number of animal can only be used to enhance and excluded. In this production needs, the 18th century there Newcomen's atmospheric steam engine to drive the mine drainage pump. But the steam engine's fuel consumption rate is high, basically only used in coal mines. 1765, Watt invented the separate condenser steam engine, reducing fuel consumption. 1781 Watt has created a steam engine to provide rotary power to expand the scope of application of the steam engine. The invention and development of the steam engine, the mining and industrial production, rail and shipping are to be of mechanical power. 19th century steam engine is almost the only source of power, but the steam engine and boiler, condenser, cooling water systems, bulky, heavy, application is very convenient. 19th century, the power supply system and the motor of development and promotion. Early 20th century, the motor has been replaced by the steam engine of industrial production as the fundamental driving force of various working machines. Production mechanization has been inseparable from the electrification, and electric production through the mechanization of fishes play a role. Early application of steam power station as the driving force. The early 20th century, there has been high efficiency, high speed, high-power turbine, also appeared to adapt to the turbine water resources, promoting the rapid development of power supply system. The late 19th century after the invention of the internal combustion engine to improve year by year, becoming light and small, high efficiency, easy manipulation, and are free to start the prime mover. It was first used to drive the work on land without power, machinery, and later for the automotive, mobile machinery and ships, since the mid-20th century for railway locomotives. Steam turbines and internal combustion engine in the exclusion, has no longer a significant power machinery. After the invention of combustion engines and gas turbine, jet engine development, the aircraft, spacecraft and other technical factors based on the successful development of one. Before the industrial revolution, machinery, mostly wooden structure, made from the wood by hand. Metals (mainly copper, iron) to produce only instruments, locks, clocks, pumps and a small wooden structure on the mechanical parts. Mainly by the metal processing machine maker Seiko secret agents, to achieve the required accuracy. The promotion of steam power plant, and the concomitant emergence of mining, metallurgy, ship, locomotive and other large machinery development requires forming and machining metal parts, and more and large, the required accuracy has become increasingly high. Application of metal materials from copper, iron, developed into a steel-based. Mechanical processing, including forging, forging, sheet metal, welding, heat treatment technology and equipment, and cutting technology and machine tools, cutting tools, measuring tools, rapid development, the development of various industries to ensure production of machinery and equipment supply. Social and economic development, the surge in demand for mechanical products. The increase of production volume and precision processing technology advances, production methods promote the formation of a large number, such as the production of parts interchangeability, specialization and cooperation, water processing line and the moving assembly line and so on. Simple interchangeability of parts and specialized division of labor production, had already appeared in ancient times. In mechanical engineering, first embodied in the Motz help interchangeability 1797 lathe thread created by the bolts and nuts produced. The same period, the United States Whitney engineers produce guns with interchangeable production methods, showing the feasibility and advantages of interchangeability. This method of production in the United States gradually extended to form a so-called "American production methods." Early 20th century, Ford created the automobile manufacturing and assembly lines. Mass production technology with Taylor in the 19th century founder of scientific management methods, so that mass production of cars and other mechanical efficiency of the production will soon reach the previously unimaginable heights. Of the 20th century, the late, mechanical processing of the main features are: increasing the processing speed and accuracy of machine tools to reduce reliance on manual skills; improve the forming process, machining and assembly of the mechanization and automation; use of CNC machine tools, machining centers, of group technology, the development of flexible manufacturing system that allows small and medium-volume, multi-variety production of production efficiency to nearly the level of mass production; research and improvement is difficult to process the new metal and nonmetal materials, forming and machining technology. 18th century, mechanical craftsmen matter of experience, intuition and craft of mechanical production, almost no contact with science. To 18 to the 19th century, in the emerging capitalist economy under the facilitation of people began to grasp the attention of scientific knowledge production, and direct the production of craftsmen are starting to learn science and culture, communication between them and made great inspiration to each other results. In the process, gradually formed a _set_ of basic theory surrounding the mechanical engineering. Power machinery first and then the combination of advanced science. Savery steam engine inventor, Watts, the application of theoretical physicists Papin and Blake; the basis of practice in the steam engine, physicists Kano, blue gold and Kelvin establish a new science - thermodynamics. Theoretical basis of the internal combustion engine Rosa France founded in 1862; Application 1876 Otto Rosa's theory, a radical improvement of the crudeness of his original creation of heavy, noisy, low thermal efficiency of internal combustion engine and laid the position. Others such as steam turbines, turbine and so in theory be developed under the guidance of, and practice theory has been improved and enhanced. Back in BC, China has the car in the guide application of complex gear system being applied in the censer can remain in the horizontal position of the aircraft and other mechanical turnstiles. Ancient Greece has cylindrical gears, bevel gear and worm records. However, the instantaneous gear ratio on the relationship with the tooth profile curve, and the choice of parties have until the 17th century theoretical explanation. Hand and pedal the crank body is a pioneer in the ancient civilization has a long history, but in the form of crank, the exact movement and dynamic analysis and synthesis, it is the achievements of modern science institutions. Of mechanism as a special subject, as late as the early 19th century was the first time included in the Higher Institute (Paris Institute of Technology) course. Through theoretical study, one can only accurately analyze various agencies, including the complex spatial linkage movement, and thus can be integrated according to need new institutions. Mechanical engineering mechanical work object is dynamic, and its work will change a lot. This change is sometimes random and unpredictable; the practical application of the material is not entirely uniform, there may be various defects; processing accuracy is the deviation, and so on. And the static structure of civil engineering for the object compared to the problems in mechanical engineering theory more difficult to accurately resolve. Therefore, the early use of simple mechanical engineering is only theoretical concepts, practical experience to work with. Design calculations and more to rely on empirical formula; To ensure safety, all conservative, which results in a large heavy machinery, high cost, low productivity, energy consumption greatly. From the 18th century, continue to the birth of new theory and the development of mathematical methods to make design calculations to continuously improve the accuracy. The 20th century, the emergence of various experimental stress analysis, experimental methods that people have been able to measure the various parts on the model and the kind of stress. Half of the 20th century, the finite element method and the extensive use of computer makes the complex machinery and parts, components for power, torque, stress analysis and calculation of such a possibility. Sufficient for the control or experimental information on the practice of mechanical or its components, has been the use of statistical techniques can, in accordance with the requirements of reliability and scientifically mechanical design.

Mechanical - Mechanical Engineering Development Outlook
Mechanical engineering to increase production and improve labor productivity, improve the economics of production as the goal to research and develop new mechanical products. In the next era, new product development will reduce resource consumption, the development of clean renewable energy, governance, and reduce and eventually eliminate the environmental pollution as a super-economic objectives and tasks. Machinery can be done with both hands and eyes of people, as well as feet, ears, and can not be directly done directly to complete the work, and completed faster and better. Modern mechanical engineering to create a more sophisticated and increasingly complex machinery and mechanical devices, so that in the past many of the fantasy become a reality. Upstream of the human is now able to sky and the universe, dive the deep ocean, far glimpse of billions of light years, close to the police cells and molecules. New computer hardware and software that humans began to strengthen scientific and technological parts of the brain instead of means, this is artificial intelligence. This new development has shown an enormous impact, in future years it will continue to create a miracle that people can not imagine. Does not reduce the growth of human wisdom the role of hands, the contrary is asking for more hands, more sophisticated, more complex work, and thus more to promote hand function. Hand turn, promote the practice of the wisdom of the human brain. The whole of human evolution, and in each person's growth process, the brain and the hands are parallel to each other for the promotion and evolution. Artificial Intelligence and the relationship between mechanical engineering is similar to the relationship between brain and hand, the difference only lies in the hardware also need to use artificial intelligence machinery out. In the past, people can not do without the operation of machinery and control the reaction speed and accurate operation by the slow evolution of the human brain and nervous system restrictions, artificial intelligence will remove this restriction. Between computer science and mechanical engineering to promote each other, parallel to the forward, will mechanical engineering at a higher level to start a new round of great development. The 19th century, mechanical engineering is still very limited amount of knowledge, universities in Europe and civil engineering in general also integrated it into a discipline, known as civil engineering, half of the 19th century gradually became an independent discipline. The 20th century, with the mechanical engineering technology development and knowledge of the total growth in mechanical engineering began to break down, has been found in specialized branches. The decomposition of the trend in the mid 20th century, that is, the period before and after the Second World War reached a peak. Integrated - Professional division - and then integrated recycling of knowledge development is reasonable and necessary process. Experts of different professions all have excellent professional knowledge, but also has enough knowledge to a comprehensive understanding of the problems in other disciplines to understand the overall appearance and engineering, work with each other to form a powerful collective. Is more comprehensive and professional level. In mechanical engineering within a comprehensive and professional conflicts; in comprehensive engineering technology also has a comprehensive and professional issues. In all human knowledge, including social sciences, natural sciences and engineering, there is a higher level, integrated with a broader professional issues.

Mechanical Maintenance
To this end, in order to make the technical maintenance of construction machinery to actually carry out, must do the following several aspects: (1) leadership and staff reached a consensus to overcome the "repair on behalf of the support" the idea, the technical maintenance of the column were an important part of maintenance management, technical maintenance will be institutionalized, and the establishment of appropriate monitoring mechanisms. (2) to strengthen maintenance and operations staff training to ensure the maintenance operation can press the "order" to In general, mechanical engineering certificates should be the driver, but the poor quality of many of the basic drivers, low level of education, there is no rigorous formal training, the construction of machinery and equipment, principles, performance and work coordination and little is known about how to improve efficiency, and technical maintenance by the main contents of the driver to complete, and therefore must formulate a series of training programs for maintenance managers, maintenance personnel, especially pilots conducted a systematic training to ensure that the operational and technical maintenance can be carried out according to procedures. (3) standardization of technical maintenance of the project content, the form of, good maintenance records and archives Maintenance of machinery and equipment specification is the technical requirements for maintenance of mechanical technology requirements. Any construction equipment in the factory when the device has been proposed routine maintenance and regular maintenance of the specific content and requirements. But people in the maintenance work, often only be qualitative and maintenance, but not exactly the content and requirements of maintenance projects to quantify maintenance. Even with no corresponding maintenance of records. Therefore, we must maintain machinery and equipment according to different project content and requirements, preparation of the corresponding technical maintenance in order to carry out maintenance forms and make a record, should establish the appropriate device file, for future maintenance and to determine mechanical condition and maintenance to provide reliable basis. (4) installed for maintenance, testing and maintenance of the equipment needed tools, try to improve the various facilities on site Many construction machinery (especially into the Japanese machinery) has detected in different parts of the point, need to use the appropriate monitoring equipment to be monitored, and in the maintenance of mechanical equipment, process technology, also need the appropriate tools and special tools used must be the complete package of tools and make a record. At the same time should be based on different environmental conditions of each site, _set_ting the table the necessary maintenance and repairs, car groove, workshops and other facilities to ensure a variety of mechanical testing and maintenance of technology can be smoothly conducted, and depending on the process of testing and maintenance of the understanding of the situation, prevention measures and make the necessary repairs, ensure that the technical state of equipment in good condition. (5) full use of funds to implement "zero inventory" management, the use of inexpensive high-quality spare parts, spare parts to be installed to prevent the use of unqualified Maintenance work in the required amount of many parts, capital consumption is also a lot of shortage of funds and therefore, they should make full use of limited funds, according to the project progress and status of machinery and equipment technology, flexible use of spare parts the "zero inventory" management method. On the vulnerable and easy to consume a small amount of funds used parts and spare parts inventory appropriate and reasonable, on time warehouse inventory, spare parts for maintenance at all levels in statistical work, to ensure that some of the necessary maintenance and use of funds more spare parts, do not delay maintenance work carried out smoothly. Meanwhile, in the purchase of spare parts, you must understand its origin, manufacturer, model, specifications and performance and other important indicators, especially some parts difficult to detect, it should to the appropriate franchised dealer or the dealer at purchase, to prevent use of unqualified parts are installed. Of course, in the purchase should shop around, inexpensive _select_ion of quality spare parts, parts for domestic and imported parts for serious comparisons between, get the best price performance ratio, to ensure that the machinery and equipment and reliable power and prolong its life, to prevent accidents. (6) taking the time and coordination between various departments, a reasonable allocation of staff to fully mobilize the enthusiasm of the staff, so that penalties and rewards According to the characteristics of various types of construction and climate change, to take full advantage of the rainy season or the time down Daigong circumstances, combined with the machine maintenance period, reasonable arrangements for machinery maintenance. At the same time, coordinate the supply of spare parts sector, construction sector and other related sector, and organizational maintenance staff and drivers to participate in maintenance, a clear mandate to fully mobilize the enthusiasm of individuals. Love machine to carry out a wide range of activities, ground maintenance, safeguard, and technical precision, high efficiency of the employees to provide financial, moral encouragement or material reward; and the result of laziness, negligence, damage caused by machinery and equipment, then be given severe punishment so learn from it. As long as we can to the technical maintenance of construction machinery and equipment to do maintenance work, you can make the machine always in good technical condition, give full play to the performance and characteristics of mechanical equipment to improve operational efficiency and economic benefits, to ensure the smooth completion of the construction tasks; You can also reduce the consumption of various types of fuel and spare parts to reduce costs, extend the life of the machine, to create more economic and social benefits.
