摘　　要：采用ANSYS商用有限元软件,对无油泵交流伺服电机直驱式新型液压机机身结构进行了静力分析和模态分析,根据分析结果对机身结构进行了相应的改进,并对改进后的机身结构进行了有限元分析,结果表明:改进后的机身机械结构静态性能和动态性能均得到了改善,满足液压机的设计要求。The commercial finite element software modal analysis of frame structure of the new type AC ANSYS has been adopted to carry out the static analysis and servo motor direct-driven hydraulic press without oil pump. According to the analysis results, the frame structure of the hydraulic press has been improved. The finite element analysis of the improved structure has been completed. The results show that the mechanical structural static performance and dynamic performance of the improved frame have been improved, which meets the design requirements of hydraulic press
