摘要

为了进一步提高和改善重载湿式离合器在使用过程的接合特性,结合分形几何理论建立重载湿式离合器接合特性计算模型,最后通过理论与试验手段获得重载湿式离合器摩擦副接触区域微凸体接触面积、分形维数及轮廓幅值尺度因素等对接合摩擦力的影响规律及湿式离合器摩擦温升变化规律。分析结果表明,不考虑微凸体作用分形维数与实际接触面积的增加,将会使湿式离合器摩擦力增加;考虑微凸体作用分形维数与实际接触面积的增加,将会使湿式离合器摩擦力降低;对于摩擦副接触面幅值尺度因素,随着其降低,将会导致各工况下摩擦力与最大温升变化幅值上升;通过试验验证,分形理论下理论计算结果与试验测定结果基本吻合。

Abstract

In order to further improve and mend the engagement characteristics of heavy duty wet clutch during the using process,the model of the engagement characteristics of heavy duty wet clutch is established by combining the fractal geometry theory.Finally,the micro convex body of the contact area,fractal dimension and contour amplitude scaling factor of the friction pair in the wet clutch contact region engagement friction force influence law and the change law of wet clutch friction temperature rise are obtained through theory and test bench method.The research results show that without considering the effect of the micro convex body,with the increase of the fractal dimension and the actual contact area,the wet clutch friction force will increase; with considering the effect of the micro convex body,with the increase of the fractal dimension and the actual contact area,the wet clutch friction force will decrease; with the decrease of the contour amplitude scaling factor,the friction force and the maximum temperature rise can be increase; the results show that the theoretical calculation between the fractal theory results and the experimental results are basically the same.
