| 摘 要： | 针对液力机械传动装置中的湿式换挡离合器,研究结合过程中影响摩擦副温度场和应力场分布的因素.运用大型有限元软件ABAQUS建立湿式换挡离合器摩擦副三维有限元模型,建模过程充分考虑了摩擦副之间的摩擦接触、相对旋转运动和热机耦合等因素,并分析了摩擦副相对转速差、对偶钢片厚度和工作油压对于对偶钢片温度场和应力场分布的影响.结果表明,高转速差使接触面中部区域的温度和应力都增加,加大盘面上的径向应力梯度.在一定厚度范围内,增加钢片厚度会加大接触面温度场和应力场分布的不均匀性.较高和较低的工作油压均会改善盘面温度和应力分布,但都会对车辆性能带来不利影响.

| Abstract: | The factors to influence on the distribution of temperature field and stress field were investigated on the plates within a wet shift clutch in hydrodynamic machineries for one engagement. A three-dimensional model of the friction pair was developed by using the nonlinear FEM software ABAQUS. In modeling process,the effect of frictional contact,relative rotary speed and thermo-mechanical coupling were taken into account. Then,the influence on thermal field and stress field was analyzed by investigating the ... |
