1、附录 Project mechanical road in where In the face of aggressive electronic industry and information industry ,several years ago, machinery industries there have been puzzled that, Some think machinery industry has become a sunset industry, lacks engage in the first, not only cost labor, but the diffic
2、ulty small profit. The actual situation? There is a need to understand and explore future industrial development. Comparable machinery for artificial animal, is the basic component of the minds, sensory organs, heart, hand, foot and bones, Then modern machinery should be a basic component is a compu
3、ter, sensors, power devices, the executive body. Intelligent animals, the information processing capability to distinguish between low and high, also by mechanical manipulation, control and information processing and functional junior and senior. Traditional machinery is the low level stage machiner
4、y, the machinery of modern machinery is in the advanced stage. The most senior of the animal, then the most senior is the mechanical robot. Modern machinery for mechanical unlimited development in the broad thoroughfare, Machinery Development, the main problems are solved with spirituality and infor
5、mation processing capabilities. Modern machinery should be clever (computer), sensory (sensors), neurological (electronic control lines), Heart (power plant) and blood (and hydraulic power transmission devices), the hands (equipment), and bone (structure). 1. Construction machinery has gone through
6、three upgrades and leap 1.1 Power revolution The small size, light weight, strong and the emergence of the internal combustion engine, the solution of engineering machinery mobile sources of power problems the engineering machinery prompted the birth and development. 1.2 Transmission revolution Solv
7、e the power problem after major problem is how to effectively transfer power to complete the operation. Mechanical engineering operations variety of forms, a wide variety of devices, the demands of a wide variety of complex campaigns. A power-driven device to a variety of devices, but often drive lo
8、ng distances, 20 1950s a liquid transmission (hydraulic and hydraulic), and construction machinery provide a good gearing. Hydraulic drive compact structure and layout is simple and convenient and easy movement of various forms of conversion, the complex can meet the operational requirements, There
9、are many excellent transmission performance; Driving a smooth, automatic prevent overload and easy to achieve CVT, the simple manipulation of light, good performance. Because of construction machinery to find the ideal transmission device, a project to promote the rapid development of machinery, ush
10、ered in the mechanical engineering diversification era, the completion of various kinds have emerged in all types of construction, construction machinery operations. 1.3 Manipulation and control of the revolution Engineering machinery and power transmission problems to solve, with the social progres
11、s and economic development and the improvement of living, mechanical engineering to a series of higher demand. Make efficient and energy-saving construction machinery, they have to engine and transmission control, and rational distribution of power, it is the best working conditions; To reduce labor
12、 intensity drivers and improving control performance, the need for automatic control, and the effort to achieve automation; To accomplish highly skilled work requires intelligent; To improve security needs security control, running and monitoring, fault automatic alarm; New areas of the building exp

What all this means is a mechanical engineering major current problem is the manipulation and control. Construction machinery should remain in the artif
14、icial manipulation stage, on the feeling that experience and technology to manipulate mechanical engineering will greatly influence the development of machinery technology, not people from the heavy, complex manipulation of the liberation of labor. In recent years the development of mechanical engin
15、eering major is the manipulation and control of the improvement, the following examples : Diesel Power Plant has been using microcomputer-controlled electronic injection and electronic governor; excavators, bulldozers and loaders are used to control engine operating conditions, according to operating conditions through electronic control, Engine power output of.
