摘　　要：为研究不同结构参数对锥形变形摩擦副承载特性的影响,建立不同结构参数下锥形变形摩擦副等效接触模型,采用Ansys Workbench进行屈曲变形仿真,结合Matlab数值模型分析,得到不同结构参数下摩擦副油膜厚度变化规律;基于油膜压力与微凸峰粗糙接触模型,探明了10 s软启动过程中不同结构参数下的最大总接触压力变化规律,总结出锥形摩擦副在满足实际使用工况条件下最优结构参数的选取方法。结果表明,钢片轴向变形与厚度的增加会使钢片中径变形更加困难,使摩擦副最大总接触压力增加,同时导致摩擦副的非均匀接触及接触压力的不均匀分布;不同内外径比只会影响摩擦副最大总接触压力的分布位置,对其变化规律与数值并无较大影响。研究结果为后续不同结构参数下锥形变形摩擦副转矩特性的研究提供了依据。In purpose of getting the influence of different structural parameters on the bearing characteris⁃tics of the conical deformation friction pair,the equivalent contact model of the conical deformation friction pair under different structural parameters is established.The buckling deformation simulation is carried out by Ansys Workbench,and combined with the analysis of the Matlab numerical model,the variation law of the oil film thickness of the friction pair under different structural parameters is obtained.Based on the oil film pressure and micro-convex peak rough contact model,the variation law of the maximum total contact pressure during 10 s soft start is found,and the method of selecting the optimal structural parameters of the friction pair under the actual operating conditions is summarized.The results show that the axial deformation and the increase of the thickness of the steel sheet can make the deformation of the middle diameter of the steel sheet more difficult,and lead to the increase of the maximum total contact pressure of the friction pair.At the same time,it leads to non-uniform contact and non-uniform distribution of contact pressure,and different ratios of inner diameter to outer diameter can only affect the distribution location of the maximum total contact pressure of the friction pair,without having any great influence on its variation law and value.The research results provide a basis for the study of torque characteristics of conical deformation friction pairs under different structural parameters.
