| 摘 要： | 根据齿轮啮合原理，准确求出复杂的齿廓曲线；采用MATALB—APDL混合建模方法，创建精确的齿轮有限元模型。在不同网格密度等级下，分别对齿轮的齿面变形、齿根应力分布进行分析。对照经验公式的计算结果，得出如下结论：在齿轮数值模拟中，由于有限元软件计算中舍入误差的存在，网格划分合理与否将直接影响仿真程度的高低；网格密度等级对齿面最大变形的仿真结果有较大影响，而对齿根应力影响甚微。

| Abstract: | Based on gear engagement principle,the exact curve of tooth profile is produced.By the method for composite modeling with MATLAB and APDL,the precise FEM model of gear is built.On the different grid density grades,the results of teeth compliances and root stresses distribution are analyzed.In contrasting with the results of experiential formulas,a conclusion can be drawn: in the gear numerical simulation,due to existing rounding error in the finite element software,grid meshing will affect evidently the sim... |
