摘要
通过三维机械设计软件SolidWorks构建液压机实体模型，运用有限元软件ANSYS对下梁进行应力分析计算，得出下梁弯曲应力分布云图。最后针对应力分布云图，对液压机结构提出了改进方案，为液压机的优化设计提供了可靠的理论依据。
The involue hydraulic press is built in SolidWorks 3D mechanic design software,then analyzes stress of underbeam by the finite element software ANSYS,so obtain the contour of bending stress distribution of underbeam.According to the countor of stress distribution,improve the structure of hydraulic press,so it canprovide the dependable basic for optimization of design of hydraulic press
