摘　　要：在10000r/min的高速状态下,考虑了滚动体与套圈滚道的结构弹性变形与动态接触关系,求解角接触陶瓷球轴承接触应力和变形,分析动力稳定性。采用有限元计算方法对高速陶瓷球轴承进行接触分析,对该轴承接触表面应力与变形的计算和仿真运动分析,绘制等效云图并将该轴承应用于高速主轴性能测试。基于ANSYS接触理论得出滚动接触体之间的相对滑动现象及其滚动体与套圈滚道相对运动关系,结果与已有的轴承运动的理论和实际情况相吻合。通过有限元计算模型表明对轴承的应力分布和动态响应是可行的,可以看出ANSYS对轴承的滚动接触理论分析有一定的指导意义,为进一步研究轴承动力学特性提供了更可靠的依据。Under the high speed 10000 rev / min,considing the structure flexible deformation and the dynamic contact relationship between the rolling elements and the ferrule raceway,Solving angular contact ceramic ball bearings contact stress and deformation,dynamic stability analysis. Contact analysis of high speed angular contact ceramic ball bearings by the finite element model,uponing contact surface stress and deformation calculation and simulation motion analysis on the all-ceramic bearing,drawthe equivalent cloud map and the bearing will be used in the high-speed spindle for performance testing. Obtaining relative slippage between the rolling contact element and the relative motion between rolling element and raceway rings based on ANSYS contact theory,the results to be consistent with pre-existing bearing movement theoretical and practical situation. Showthat the stress distribution and the dynamic responses in bearing by finite element model is feasible,it can be seen ANSYS has a certain significance on bearing rolling contact theory,providing a more raliable basis for further study bearing dynamics analysis and fatigue life of the bearing.
