基于ANSYS Workbench的深沟球轴承接触应力有限元分析

摘要

利用ANSYS Workbench软件建立了深沟球轴承的三维非线性接触模型,对模型的边界条件进行合理的设置后,基于有限元的方法,在Static Structural(ANSYS)中对深沟球轴承的接触应力和变形进行了仿真计算,得到了轴承滚动体和内、外圈不同部位接触应力和变形的分布.计算结果与Hertz理论解进行了对比,两者具有良好的一致性,说明了用ANSYS Workbench分析滚动轴承接触问题是可行的,符合轴承在载荷作用下受力和变形的实际情况；有限元仿真计算的结果为滚动轴承的设计、优化和失效分析提供了参考依据,具有一定的工程实用价值.%The 3D nonlinear contact model of a deep groove ball bearing was established in ANSYS Workbench sofiware.With the reasonable setting of the boundary conditions,the contact stress and deformation were calculated in Static Structural (ANSYS)by using the finite element method,and the contact stress and deformation of the inner ring, the outer ting and the rolling elements were obtained.Furthermore the computational values are consistent with the Hertz values.The results show that solving the bearing contact problem with ANSYS Workbench software is feasible and it coincides with the stress and deformation of the actual situation.The FEM results provide reference for the design, optimization and failure analysis of rolling bearings and have practical engineering value.
