摘　　要：为了解湿式双离合器摩擦副工作表面发热状况,建立了摩擦副三维有限元模型,借助于AcuSolve软件对其进行瞬态温度场仿真分析研究。以弹射起步工况为研究对象,探究摩擦副主、从动端转速差、接合时间以及峰值油压等因素对钢片温度场的影响规律。仿真结果表明:沿对偶钢片径向表面,温度随着半径的增加而减小,最高温聚集在方型槽处;主、从动端转速差越大,对偶钢片径向表面温度梯度越大;增加接合时间会导致对偶钢片表面温度大幅升高;峰值油压越大,对偶钢片径向表面温度梯度越小,表面温度越高。In order to understand the thermal condition of the working surface of the wet double clutch friction pair,a threedimensional finite element model of the friction pair was established.The transient temperature field simulation analysis was carried out by means of AcuSolve software.Taking the ejection starting condition as the research object,the influence of the factors such as the speed difference between the driving end and the driven end of the friction pair,the bonding time and the peak oil pressure on the temperature field of the steel sheet are investigated.The simulation results show that along the radial surface of the dual steel piece,the temperature decreases with the increase of the radius,and the highest temperature gathers at the square groove.The larger the rotation speed difference between the driving and driven ends,the greater the radial surface temperature gradient of dual steel sheet;increasing the bonding time will lead to a large increase in the surface temperature of the dual steel sheet;the larger the peak oil pressure,the smaller the radial surface temperature gradient of the dual steel sheet and the higher the surface temperature.
