摘　　要：采用Winkler模型,分别对自润滑关节轴承受径向载荷和轴向载荷时的接触应力计算公式进行推导,再利用ANSYS软件对轴承受径向载荷和轴向载荷时的接触应力分布进行有限元分析,将理论计算结果和有限元结果进行比较,二者误差较小,证明了理论公式的合理性,该公式可用来计算不同型号自润滑关节轴承的接触应力。The calculation formula for contact stress of self- lubricating spherical plain bearings which are respectively subjected to radial load and axial load are derived by using Winkler model,and the FEA for contact stress distributions of bearings is carried out by using software ANSYS. The theoretical calculation results are compared with the finite element results. The smaller error proves the rationality of theoretical formula. The formulas can be used to calculate the contact stress of different types of self- lubricating spherical plain bearings.
