摘　　要：利用CATIA软件建立一个正六面体模型,导入到HyperWorlds中进行不同约束方式的三种工况静力学分析,得到位移和应力分布图。计算出典型工况下六面体的变形位移与应力大小,同软件结果进行对比,分析其误差范围及原因,由此总结出不同约束方式对静态有限元分析结果的影响。Establish a regular hexahedron model by using CATIA software,import it into the HyperWorks for static analysis under three different kinds of working condition and constraint ways,and then get the displacement and stress distribution？ Calculate its deformation displacement and stress in the typical working condition,comparing with the software results to analyze its error range and reasons,finally,summarize the influence of different constraint ways of static finite element.
