盘式制动器平均摩擦系数的试验研究
Experimental research on average friction coefficient of disk brake
【摘要】 利用制动器惯性实验台,通过具体试验来分析某盘式制动器的平均摩擦系数受制动压力、制动速度和制动温度3个主要因素的影响情况。分别在其中一个因素确定的情况下,测试平均摩擦系数受另外2个因素变化的影响的情况,由测试数据进行二次回归得出计算式来描述平均摩擦系数受影响因素的变化情况。对回归方程都进行了显著性和失拟检验,检验表明回归方程结果显著、拟合效果良好。
【Abstract】 The influence on average friction coefficient of disk brake caused by pressure,speed and temperature factors was tested.The tests were conducted under one factor predefined,the other two changed in a range.Then based on analysis on the results by using quadric recursive method,three formulas were got to describe the average friction coefficient change affected by relative factors.
