Pro/Engineer与ANSYS进行零件有限元分析的差异研究 The Difference between Pro/Engineer and ANSYS in FEA

为了了解零部件应力的分布与变形情况，通过有限元分析技术可以仿真模拟零件在相应载荷和约束下所对应的变形，本文分别利用两种不同软件Pro/Engineer和ANSYS对零件进行静力学有限元分析，ANSYS采用有限元分析，不同的网格划分对结果影响很大，Pro/E则采用几何单元网格划分，所求应力比ANSYS所求应力略大，比较结果，分析原因以得出在确定条件下选取更优的方法求解零部件的应力分布与变形。 To get the stress distribution and deformation of mechanical parts, we can imitate the stress and deformation under the load and restraint by FEA. This paper does static analysis for parts by using Pro/Engineer and ANSYS. Different meshes will affect the result seriously, because FEA is used in ANSYS, but GEA is used in Pro/E. As a result, the stress in Pro/E is little bigger than in ANSYS. The more suitable method for solving the stress and deformation under some condition is gotten by comparing the two results and analyzing them.
