通过分析湿式离合器的接合过程，应用一维平均雷诺方程和粗糙表面弹性接触模型建立湿式离合器接合过程数学模型。利用龙格-库塔数值方法对接合过程数学模型进行求解，研究湿式离合器接合压力对接合过程中黏性转矩、粗糙摩擦转矩及传递转矩的变化规律。仿真结果表明：接合压力上升越慢，其产生的黏性转矩、粗糙摩擦转矩及传递转矩响应越慢；接合压力上升特性对黏性转矩和粗糙摩擦转矩的峰值影响较小，对黏性转矩总体变化趋势影响也较小，但对粗糙摩擦转矩和传递转矩总体变化趋势影响较大。

By analyzing the wet clutch engagement,the mathematical model of wet clutch engagement based on one-dimensional average Reynolds equation and elastic contact model between asperity sur-faces was established. We got the solution of the mathematical model during engagement process by u-sing the Runge-Kutta numerical method to study the changing rules of wet clutch to viscous torque, friction torque and transmitted torque in engagement process. Simulation results show that the slower the engagement pressure rise,the slower the viscous torque,friction torque and transmitted torque re-sponse,and the rise characteristics of engagement pressure have a less impact on the peak of viscous torque and friction torque and it has little impact on the overall trend of viscous torque,but it have a greater impact on the overall trend of friction torque and transmitted torque.
