针对宽斜齿轮，提出了轮齿在不同位置啮合时有限元网格及模型的自动生成方法，并开发出相应的三维前后处理及接触分析程序，进行了轮齿啮合过程中应力应变的数值分析。本文程序使用方便，只需输入齿轮基本参数，即可得到轮齿不同啮合位置的网格、应力分布、位移场、应力场、接触状态及接触线载荷分布。 Aiming at the problem of wide bevel gear, a method of automatic generation of finite element mesh and model when gear teeth meshing at different positions is proposed. The corresponding three-dimensional preprocessing and contact analysis program is developed, and the numerical analysis of stress and strain during gear meshing is carried out . This program is easy to use, just enter the basic parameters of the gear, you can get the gear meshing position of different mesh, stress distribution, displacement field, stress field, contact state and contact line load distribution.
