Of modern Chinese language the word Machine is organization is (Mechanism) of the English and the floorboard of the Machine (the Machine). Mechanical characteristics are: machinery is a combination of physical components. To determine the relative motion of mechanical parts. So the Machine can convert mechanical energy or accomplish useful mechanical work, is the most basic concept in modern mechanical principle, the modern concept of Chinese machinery more derived from the word Machine of the Japanese, Japanese machinery should supplies to do the following definition (that is, in accordance with the following three characteristics is called mechanical Machine) :1, the machinery is a collection of objects, concentration to the various parts are also difficult to deformation.2, the object must implement the mutual movement, single, regulations.3, to exert energy into a useful form, or converted into mechanical work effectively.Mechanism and machine definition is derived from the mechanical engineering, belongs to the most basic concept of modern mechanical principles, mechanical more modern concepts derived from Chinese of the word machine in Japanese.All have certain sports machine and the floorboard of the system. Such as machine tools, tractors, etc.Mechanical engineering is related to the theoretical basis of natural science and technology,Mechanical gear (figure 2) combined with the accumulation of technical experience in the production practice, study and solve in the development, design, manufacture, installation, use and repair of all kinds of machinery an applied subject of theoretical and practical problems.Every development in the field of engineering requirements in mechanical engineering has adapted to the development, need mechanical engineering provides the necessary machinery. Some mechanical invention and improvement, and could lead to new engineering technology and the emergence and development of new industry. Large machinery manufacturing success, for example, led to the establishment of electric power system; The invention of the locomotive led to the rise of railway engineering and railway undertakings; The invention of the internal combustion engines, gas turbines, rocket engines, etc and progress, as well as the successful development of aircraft and spacecraft has led to the rise of aviation and aerospace business; The development of high voltage equipment lead to the success of many new synthetic chemical engineering and so on.Mechanical engineering is in all respects under the pressure of rising demand for development, at the same time from different disciplines and the advancement of the technology improved and innovative ability.Machinery is a simple device, it can transfer energy, force from one place to another place.Mechanical gear (FIG. 3) it can change the shape of the object structures to create new objects. In life, all around us there are thousands of different kinds of machinery in the work for us.Everyday understanding of mechanical is a mechanical device, which is all kinds of machines and equipment.From the point of view of mechanical professional: machinery has a very important basic position.Machinery is a modern society the five factors of production and service (that is, people, money, energy, materials and machinery).When Marx to industrial society, industrial society, especially in big industrial society, which is machine production machine age.Whether from life in contact with all kinds of physical devices, such as telephones, electric lights, television, refrigerator, elevator and so on contains the machine, or included in the general machinery, and from the point of production, all kinds of machine tools, automation equipment, aircraft, ships, god five, six, and so on, are short of machinery.So, machinery is one of the foundations of modern society. If someone say agriculture is the foundation, also understandable, but in modern society, mechanical serve as the basis for the rest of the industry and engineering, it is no exaggeration to think is the big pillar in society.Any modern industrial and engineering applications require machinery, is the Peoples Daily life, are increasingly used all kinds of machinery, such as cars, bicycles, watches and clocks, cameras, washing machine, refrigerator, air conditioner, vacuum cleaners, etc.The first machine is defined as the Roman architect vitruvius pollio (Vitruvii) in itMechanical gear (figure 4) for building ten book mainly for carrying heavy things work machinery and tools: the difference between mechanical (machane) and tools (organon) seem to have the following differences between. The machine is most artificial and very big power and effect, such as heavy ballista and grapes press. While the tool is a manipulation of the staff carefully processing, to achieve the purpose of such as were the shape of light range ballista or circular spiral device. Thus, tools and machinery are used in the indispensable thing. The ancient Greek for cylindrical gears. Alexandria, Mr Hiro (Heron of Alexandria) in the 1st century first discussed the basic elements of machinery, mechanical elements considered to be five classes: wheel and shaft, lever, pulley, wedge, spiral. Hiros discourse reflects the classical mechanical characteristics. BC China has guidelines on the application of complex gear system, the incense burner in the application of the permanent control level of the bogie and other parts of a cross. Annotations, said: the machine, the crossbow tooth; enclosed, the arrow around. Said wen jie zi explanation of machine is machine, the main mover , refers to the crossbow.Mechanical in leipzig, Germany in 1724 and liao poulter (Leopold) is defined as machines or tools is a kind of artificial device, use it to produce favorable movement; at the same time cant use other ways to save time and power, it can save. British mechanics, Willis (truly illis) in its agency theory (The Principle of Mechanism, 1841) give The definition of:Machinery gear speed reducer any machine (machine) are made in a variety of different ways of connecting a set of artifacts that make it a component, the component will happen in a certain sport, these artifacts and the initial movement of the components of relative motion relationship depends on the nature of the connections between them. German machinery at le loro (F.R euleaux) in the theory of kinematics (Theoretische Kinematik, Grundzuge einer TheorieChina is the worlds first national machinery development. Chinese mechanical engineering technology not only has a long history and splendid achievements in Chinese is not only the material culture and social economic development plays an important role in the world, and to promote the progress of civilization, technology has made great contribution to Chinese traditional machine. And in a long period ahead in the world. In modern times, especially from the early 18th century, due to the nineteen forties, due to the economic and social reasons, such as the China machinery industry, stagnation, in the 100 years is western bourgeois political revolution and industrial revolution, mechanical science and technology is developing rapidly, and far more than the level of China. So, China mechanical development level and the western gap widens, sharply to the 19th century middle behind western one hundred years.After the founding of new China, especially in the past 30 years, our countrys mechanical science and technology development speed. To the mechanical product large-scale, precision, automation and discusses the trend of development. In some aspects has reached or exceeded the world advanced level. Generally speaking, currently China mechanical science and technology achievement is huge, developing fast, high level of unprecedented. In this period, China has no end of mechanical science and technology will develop to a higher level. As long as we can adopt the correct policy, with good technology development and innovation, our machinery industry and mechanical technology can revitalize, leading to the development trend of mechanical industry.Just small ramming machinery:In the 1960s, China mechanical very small tamp lack, many small venues ramming basically USES artificial ramming.Early 1960s, changsha construction machinery institute and Beijing architectural engineering institute, etc., the technical innovation achievements in mass on the basis of summing up Chinese characteristic invented the breaststroke ramming machine, 1962 exceeded national science and technology.
