Progress and Prospect of research on Mechanical Engineering in China
In twenty-first Century, human society faced four major problems: climate warming, resource depletion, population growth and environmental degradation. As time goes on, these problems will become more and more serious and insurmountable. People will find that ecology (the protection of the earth and the environment of human existence) may be more important than the economy. China will be the largest energy consuming country in the world. 20 years later, due to the depletion of oil and coal, the proportion of nuclear energy, solar energy, geothermal energy, wind energy and hydraulic energy will increase significantly. Manufacturing in the future is still one of the main means to create wealth of human civilization and promote human progress. The manufacturing industry is a pillar industry of the national economy, and it supports the other industries to promote ecological construction and economic growth. Faced with the above major problems, the manufacturing industry and its science and technology are facing severe challenges. Because China will realize the strategic transformation from "manufacturing country" to "manufacturing power", to achieve this strategic transfer, the key lies in the innovation of manufacturing technology and its products. The competition between manufacturing industries is, in the final analysis, the competition of science and technology. Product innovation and independent brand building are important challenges for China's manufacturing industry.
If we can correctly recognize, predict and face these challenges, take the strategy and strategy in time, and strengthen the original innovation and independent innovation of manufacturing technology and its products, China will become a powerful manufacturing country. China's high-end brand products will keep pace with the United States and Japan, and China's manufacturing industry will stand in the forest of the world.
This article is the core of the comprehensive report of the "2008~2009 mechanical engineering discipline (mechanical manufacturing) development report" compiled by the China Association for science and technology. This paper tries to make a review of the main new views, new theories, new methods and new technologies and achievements in the field of mechanical engineering in recent years. By using Delphy investigation and research analysis, the future of the development of the subject was predicted scientifically, and the development trend of the mechanical engineering discipline in the next 5~10 years and even longer period was prospected, and the priority areas and important scientific and technological problems in the future development of the discipline of mechanical engineering in China were put forward. Due to the limitations of time, information and knowledge, the omission and errors in this article are welcome.
The definition and scope of mechanical engineering discipline is the science of the theory, method and technology of the performance, design and manufacture of mechanical systems and products, including two fields of mechanics and manufacturing science.

2. Review of the progress of mechanical engineering research in China
Mechanical engineering research is an inexhaustible source of advanced manufacturing technology. The main driving force for promoting the independent development of China's manufacturing industry is advanced manufacturing technology. Advanced equipment for aerospace and national defense is almost entirely based on independent innovation technology. In aviation, vehicles, home appliances, microelectronics, light industry, petrochemical, construction machinery and other manufacturing industries, independent innovation technology and independent brands are also increasing.
Under the support of the National Natural Science Foundation, mechanical engineering research has made a series of outstanding progress and original achievements in recent years.

Wen Shizhu and Luo Jianbin found a transition zone between dynamic lubrication and boundary lubrication, and proposed the concept of film lubrication, the invention of nano film measurement technology, and the establishment of the physical and theoretical model of film lubrication. The study of film lubrication has built a bridge between dynamic lubrication and boundary lubrication, which is considered as "an important contribution to the research of lubrication" by the famous expert GRANICK in the world. The National Key Laboratory of tribology has recently established the theoretical model of fast adhesion and desorption in house lizard crawling, and coupled the theory of molecular membrane gas lubrication with the effect of surface force in the relationship between the micro adhesion and the biological movement of the nano scale interface. The effect of van Edward force on the flight characteristics of the magnetic head in the motion equation of the magnetic head was found. In the study of interface drag reduction, the new theory and new technology of micro vortex, micro convex body and micro cavitation drag reduction are put forward in the study of interfacial drag reduction, which has greatly reduced the friction resistance of the surface.

On the platform of planar 3 degree of freedom parallel compliant mechanism, Zhang Xianmin and other low coupling precision positioning mechanisms, which consider the natural frequency, maximum stress and maximum driving force, have been applied in the electronic manufacturing equipment.
2.3 field of mechanical dynamics
Nonlinear dynamics, fault prediction and intelligent maintenance of complex electromechanical systems are frontier research fields of mechanical dynamics.
In the bifurcation study of high dimensional nonlinear systems, Chen Yushu has proposed the constraint bifurcation theory, the time variant generation system's security domain erosion theory and the nonlinear rotor system stability quantitative analysis method.

陳學(xué)東在高速超精密運(yùn)動控制研究中,率先發(fā)現(xiàn)并闡明了氣浮軸承氣旋現(xiàn)象產(chǎn)生的機(jī)理,提出了氣浮氣膜的支撐剛度和阻尼的計算和控制方法,提出的驅(qū)動系統(tǒng)分析控制軟件已經(jīng)用于我國大規(guī)模集成電路光刻機(jī)驅(qū)動系統(tǒng)的研制中。 針對船舶推進(jìn)系統(tǒng)中軸承使用貴重金屬、以及用油做潤滑劑造成河海污染問題,王家序等提出了一種新型復(fù)合材料水潤滑動密封軸承,揭示了載荷、速度、時間、間隙、溫度等因素對水潤滑橡膠合金軸承摩擦磨損性能的影響規(guī)律,發(fā)明了具有多曲面與直線圓弧凹槽有機(jī)組合的水潤滑橡膠合金軸承。由于這種軸承節(jié)省了大量貴金屬、以自然水代油做潤滑劑大大減少了對河海水的污染,在國內(nèi)外船舶等傳動系統(tǒng)中得到廣泛應(yīng)用。
