摘　　要：以B7008C轴承为例,基于ANSYS Workbench运用局部网格细化方法对角接触球轴承接触应力进行计算,计算结果与Hertz理论解对比,验证了有限元法的正确性。并通过有限元法分析结构参数对接触应力的影响,结果表明:随钢球半径参数的增大,最大接触应力值呈线性减小;存在最优内外圈沟曲率半径系数使钢球与内外圈接触的接触应力相等,且此时轴承最大接触应力值最小。Taking bearings B7008C as examples,the contact stress of angular contact ball bearings is calculated by using local grid refinement method based on ANSYS Workbench,and compared with Hertz theory solution. The effect of structural parameters on contact stress is analyzed through FEM. The results show that the maximum contact stress value decreases linearly with the increase of steel ball diameter. The optimum groove curvature radius coefficient of inner and outer rings are existed to equal the contact stress of steel balls,inner and outer rings,the maximum contact stress value of bearings is minimum at this time.
