Experiment　and Study on Friction Characteristics of a PaperBased Friction Material in Wet Multiple Disc Brakes

摘要: 湿式多片制动器纸基摩擦材料摩擦特性受其工作条件的影响非常显著。该文通过对制动器盘片温度、速度和衬片压力等因素的正交试验分析，阐明了各项因素及其交互作用因素对其摩擦特性的影响程度，推导出制动器平均摩擦系数与盘温、速度和衬片压力等因素之间的回归方程，从而为新型湿式多片制动器的设计提供理论依据。

Abstract: The performance of paperbased friction material in a wet multiple disc brake is greatly influenced by working conditions. In this paper, the effects of several major factors，such as the plate temperature， speed，lining pressure and the interactions among the factors were investigated in orthogonal experiment using an inertia dynamometer． The regression equation on average friction coefficient was derived． It provides a theoretical basis for designing a new wet multiple disc brake.
