It aims at the high speed bearings'failure questions existing nowdays.Based On the finite element method,it establishes 3D analysis model of high-speed rolling bearing in ANSYS Workbench.With the reasonable boundary condition,every contact stress and deformation of rolling element with the inner ring and outer ring is calculated in the model,then obtaining the values of every contact stress and deformation of rolling element with the inner ring and outer ring,the contrast diagram of 3 rolling body and 1 rolling element,drawing the changes condition of the different rolling body's contact stress and deformation under the same increment and the contact area changes of different rolling body under the same force.The computational values are consistent with Hertz values.The results show that the model and boundary condition are rational and correct.The obtained every contact stress and deformation of rolling element provides theoretical guide for the bearings 'failure analysis and design.
