本文在三维弹性接触边界元法的基础上根据滚子轴承的特点采用面力子单元和板(间隙)单元求解了多列滚子轴承的三维接触压力分布。本方法综合考虑了内外座圈及中间滚子弹性变形的影响,与模拟实验的实测数据相比较具有较好的一致性。本文方法具有数据准备简单、计算速度快、精度高等优点,为求解多列滚动轴承三维接触压力分布提供了一种有效的数值解法。 Based on the three-dimensional elastic contact boundary element method, the three-dimensional contact pressure distribution of multi-row roller bearings is solved by using the unit of face force and plate (gap) based on the characteristics of roller bearings. The method takes into account the influence of the elastic deformation of the inner race and the middle roller, and has good consistency with the measured data of the simulation experiment. This method has the advantages of simple data preparation, fast calculation speed and high accuracy. It provides an effective numerical solution for solving the three-dimensional contact pressure distribution of multi-row rolling bearings.
