一、国内外情况概述作用在齿轮上的载荷主要是啮合点的作用力和从轴上传来的扭矩,如果忽略偏载,可以认为这些力都作用在齿轮平而之内,因而齿轮的计算可以看成是一个平面应力问题。从理论上讲,用有限元方法对平面应力问题进行计算是不存在任何问题的。但在具体进行计算时我们发现,由于在齿根存在着应力集中现象,那里网格必须分得很密,这就对计算机容量提出了比较高的要求,计算
First, the situation at home and abroad Overview The role of the load on the gear is mainly the meshing point of the force and the shaft from the torque, if you ignore the partial load, you can think of these forces are acting on the flat gear, so the gear calculation Think of it as a plane stress problem. In theory, there is no problem with using the finite element method to calculate the plane stress problem. However, in the specific calculation, we found that due to the existence of stress concentration in the root, where the grid must be very dense, which put forward a relatively high computer capacity requirements calculated
