摘　　要：根据回转支承的受力及结构特点,应用滚动轴承载荷理论,对三种极端工况下滚动体的载荷分别进行了计算,得到最大接触应力值。建立回转支承的简化模型,利用ANSYS有限元仿真分析软件进行强度分析,得出三种工况下每排滚子接触强度的有限元仿真结果,与理论计算结果对比相接近,验证了三维接触模型的网格划分、接触算法、载荷和约束的施加等研究方法的正确性,理论计算与数值模拟相互佐证,表明分析计算的可靠性。计算结果表明在长期承受较大的接触应力作用下,最终使滚动体受载作用严重,出现裂纹、点蚀等情况。According to the stress and structural characteristics of the slewing bearing,this paper applies the rolling bearing load theory to calculate the load of the rolling element under three extreme conditions,and obtains the maximum contact stress.The simplified model of the slewing bearing is established,and the strength analysis is carried out using the ANSYS finite element simulation analysis software.The finite element simulation results of the contact strength of each row of rollers under three working conditions are obtained,which are close to the theoretical calculation results.The correctness of the research methods such as mesh division,contact algorithm,load and constraint application of the three⁃dimensional contact model is verified.The theoretical calculation and numerical simulation are mutually supportive,indicating the reliability of the analysis and calculation.The calculation results show that under the action of long⁃term large contact stress,the rolling element will eventually be heavily loaded,with cracks and pitting corrosion.
