摘要/Abstract

摘要： 针对湿式离合器局部润滑及摩擦特性的影响因素，建立了摩擦副微观混合润滑模型。考虑了微凸峰接触和局部温升的影响，分析了转速对湿式离合器摩擦副局部压强分布、油膜和微凸峰承压比、实际接触面积、局部温升的影响。同时，利用摩擦磨损试验机进行小试样柱销-摩擦盘试验，分析了不同转速下离合器摩擦系数变化规律。结果表明：随着速度的增加，润滑油膜动压作用显著增强，摩擦副实际接触面积明显减小，法向载荷最终主要由润滑油膜承担；摩擦系数主要受微凸峰实际接触面积变化的影响，变化规律与微凸峰实际接触面积呈大致对应关系。

Abstract: This work focuses on the influence of rotating speed on local lubrication and friction charac- teristics of wet clutch. A thermal mixed lubrication model in plane contacts is developed, and the pin-on-disc tests are conducted on universal material tester (UMT). Local pressure distribution, load sharing ratio, contact area ratio, local temperature rise and friction coefficient are analyzed. The results show that, as the rotating speed rises, hydrodynamic pressure grows significantly, while real contact area of friction pair reduces obviously. The main normal load is supported by hydrodynamic film. The friction coefficient is mainly affected by the change of asperity contact area, and has rough congruent relationship with the real contact area ratio. Key
