摘　　要：为了改善三叉式万向联轴器滑杆-套筒孔接触副的润滑状况,基于分形理论建立了联轴器滑杆-套筒孔接触副的弹流润滑计算模型,并结合某小型汽车一挡工作条件,基于modeFrontier软件和NSGA-Ⅱ算法对联轴器润滑性能进行多目标优化。优化后联轴器的最优参数较优化前最大油膜压力降低了27.3%,中心油膜厚度增加了72.7%,且优化结果与数值计算结果误差不超过5%。In order to improve the lubrication condition of the slider-sleeve bore contact pair of the tripod sliding universal coupling,the calculation model of elastohydrodynamic lubrication of the slider-sleeve contact pair is established based on fractal theory.By means of modeFrontier software and NSGA-Ⅱ algorithm,a multi-objective optimization of the coupling lubrication performance is carried out under the first gear operating conditions of a small vehicle.After optimization,the maximum oil film pressure is reduced by 27.3%,the central oil film thickness is increased by 72.7%,and the error between optimization results and numerical results is less than 5%.
