摘要
为研究湿式离合器摩擦副接合过程的温度场影响因素,采用ABAQUS6.14的直接耦合方法对湿式离合器摩擦副进行仿真分析,研究了初始滑摩转速差和工作油压施加速度对摩擦钢片径向、轴向以及周向温度场的影响规律。仿真结果表明:随着初始滑摩转速差的增加,摩擦钢片最高温度升高,温度梯度沿径向和轴向方向增大,摩擦钢片外齿对周向温度场影响变小;不改变总的滑摩时间,随着工作油压施加速度加快,摩擦钢片最高温度升高,温度梯度沿径向略有变大,对摩擦钢片轴向和周向的温度场影响较小。
During the engagement of wet clutch,the influencing factors of the temperature field are investigated base on the direct coupling method in ABAQUS6. 14. The influence on the radial,axial and circumferential temperature fields of separator plate was analyzed by investigating the factors of initial speed difference and working oil pressure acceleration. The simulation result shows that higher initial speed difference results in higher rise of maximum temperature on separator plate, the temperature gradient along the radial and axial direction becomes larger,and the influence of external teeth on distribution of circumferential temperature field becomes smaller. Besides,higher working oil pressure acceleration（ without changing the total time of slipping） also results in higher rise ofmaximum temperature on separator plate,but slightly rise of radial temperature gradient and negligible influence on temperature field along axial and circumferential direction.
