摘　　要：从3个力学计算的经典模型出发,分别运用ANSYS程序中的不同单元类型和不同的单元划分密度,比较了它们的计算精度,结合有限元数值解的收敛理论,阐述了有限元分析计算中,技术人员对计算结果正确性判定,应该注意的几个问题.Based on three classic mechanical models, the writer gives their data solution of finite element method （FEM） in the ANSYS software and compares these solutions with theory solutions. By means of the data theory of FEM some results about the analysis accuracy of data solution are derived from the study. These results can help the technicians improve the skill using the FEM.

关 键 词：单元类型 单元密度 计算精度
