中文摘要:
      建立汽车起步离合器的动力学模型,仿真计算出汽车起步时离合器结合产生的滑磨功及摩擦片与周围空气 的对流换热系数;建立摩擦片的有限元模型并进行热结构耦合分析。结果表明,汽车起步时,离合器接合摩擦片最高温 度达到了755℃,摩擦表面温度由摩擦片内缘向外逐渐升高;汽车起步时摩擦片最大热变形量达到00114mm,其热 变形形式为径向膨胀,轴向波浪式翘曲变形。
英文摘要:
      The mathematical model of clutch combination process was established,and the clutch friction work in vehicle start process and the convective heat transfer coefficient of friction plate with air were calculated.The finite element model of the friction plate established and thermo-mechanical coupling analysis of the friction plate was performed.The results show that the highest temperature of friction plate reaches to 75.5 ℃ in the start process of vehicle.The friction surface temperature is gradually increased from the inner edge to the outer edge of friction plate.Maximum thermal deformation reaches 0.011 4 mm in the start process of vehicle.The friction plate heat distortion is radial expansion,axial waves warping.
