摘　　要：建立湿式摩擦离合器接合过程中摩擦片流固耦合瞬态传热模型,考虑摩擦片与对偶片的热流分配问题,计算湿式摩擦离合器摩擦片的温度场和对流换热系数,得出摩擦片温度场径向和周向的分布规律以及最高温度的变化规律,分析径向槽摩擦片不同油槽倾角对摩擦片瞬态温度场的影响。结果表明,制动过程中摩擦片最高温度随着油槽倾角的增加有先减小后增大的趋势;最高温度出现的位置随着滑摩时间的增加逐渐向摩擦片内径处靠近;越靠近摩擦盘的外边缘,摩擦片的周向温度梯度越大。The fluid-structure coupled transient heat transfer model of the wet friction clutch was established, consider- ing heat flux allocation between the friction plate and the dual plate, the temperature field and transfer coefficient were cal- culated, and the change regulation of the radial and circle temperature distribution and peak temperature were obtained. The effect of the oil groove tilt angle on the radial groove friction plate transient temperature field was analyzed. The results show that the temperature peak of the friction plate is decreased first and then increased with the increase of the oil groove tilt angle at the braking process. The position of temperature peak is becoming close tO the inner radius as time goes by, the closer the position to the outer radius, the bigger the temperature gradient of the friction plate is.
