摘　　要：湿式离合器中的摩擦副在带排阶段,由于润滑剂的粘性流体特性,在摩擦副存在相对运动条件下会产生带排扭矩和能量损失,这种现象严重影响使用寿命,减少产品的安全性。针对这一问题,基于Navier-Stokes方程,采用有限元数值模拟仿真的方式,设计分析了12种槽型共24个油槽方案探索降低带排扭矩和能量损失的方法 ,结果表明螺旋槽与径向不通槽组合设计冷却效果好,动摩擦因数高,实验结果为摩擦片油槽设计提供了重要的参考依据,具有重要的指导意义。The friction pairs in wet clutches can cause drag torque and associated energy loss,when friction discs are not engaged,due to the viscous fluid nature of the lubricant subjected to relative motion between the friction pairs.This phenomenon is detrimental to the service life of wet clutches and causes concern of risk.In addressing this issue,based on the Navier-Stokes equation,a total of 12 groove designs with 24 configurations are designed and analyzed by means of finite element numerical simulation to explore the methods of reducing the drag torque and energy loss.The results show that the combination of spiral groove and radial non-slot design has good cooling effect and high dynamic friction coefficient.This paper provides an important reference for the design of friction pairs oil grooves,which is of great significance for guidance.
