机械构成元素与加强型机械的研发

Abstract Machinery has become an indispensable tool in today's world. In the industrial field mechanical processing industry isdeveloping rapidly. To understand mechanical principle and processing principle is essential to ensure that mechanical products is suitablefor industry development and guarantee of its quality and effect. Starting from the analysis of mechanical components this article illustratesthe basic structure of mechanical principle then points out the present situation of the use of heavy-duty machinery and its research anddevelopment and puts forward the problems and countermeasures in heavy-duty machinery research and development in China.院机械构成元素 加强 研发Key words mechanical constitute elements strengthen research and development中图分类号院F407 文献标识码院A 文章编号院1006-4311（2014）31-0209-02
