| 摘 要： | 湿式离合器在实际啮合过程中,离合器摩擦片高速运转,摩擦副接触为2个随机粗糙表面的接触,因此分析离合器啮合过程必须考虑摩擦片惯性及摩擦副表面粗糙度的影响.采用Greenwood-Tripp两粗糙表面接触模型,并考虑惯性的影响,对主动盘下表面有摩擦材料的湿式离合器的啮合过程进行分析,建立基于Patir-Cheng平均流量模型的研究模型,推导出摩擦副的润滑控制方程,并进行求解.理论计算得出的啮合转矩变化与实验结果相吻合,验证了理论分析的正确性.

| Abstract: | During the engagement of wet clutch,the friction disks run at high speed,and the surfaces of two friction disks are rough at random,so the surface roughness and inertia interaction of friction disks must be considered at analyzing the engagement of wet clutch.Based on Greenwood-Tripp asperity contact model and considering the influence of inertia,the engagement of friction coupling of wet clutch with friction material behind driven disk was investigated.The research model was established based on the average flow model of Patir-Cheng,and the hydrodynamic governing equation derived and solved.The theoretical data obtained from changes in the engagement torsion agreed well with the experimental data,which verifies the correctness of theoretic analysis. |
