| 摘 要： | 首先对一实例进行理论计算,然后对其进行有限元分析,并对不同网格划分状态下的模型计算结果与理论结果进行比较。最后对有限元分析误差进行评估及原因分析,并得出有限元分析计算时网格划分并不是越细小越好,关键是＂适度＂的结论。

| Abstract: | In this paper,a certain example was firstly calculated theoretically,then analyzed by ANSYS,and the theoretical result was compared with the FEA results of different meshed molds.Finally,an error evaluation was given about the results by FEA and error reason was also analyzed.So a conclusion that the mesh is not the smaller the better when you analyze through FEA is educed,the key point is to choose a proper mesh size. |

| Keywords: | FEA meshing error evaluation |
