【摘要】 针对鼓式制动器在高制动初速、高气压下制动力矩的台架试验值与设计值存在较大偏差的问题,对试验测量的制动器制动力矩进行二元线性回归分析,建立了鼓式制动器的幂函数摩擦模型。进行了显著性检验和失拟性检验,检验结果验证了所建立的摩擦模型有效,可提高整车制动效能模拟计算精度。更多还原

【Abstract】 The bench test results of brake drum show that measured values have the big deviation from design values of brake torque in the high brake initial speed,the high brake pressure.Based on the binary linearity regression analysis of experiment tests of brake torque,the friction model of exponential function is established.Proceeding tests of significance and loss-faulty,the tests results proved the friction model is valid,and can improve the complete vehicle brake efficiency simulation account precision.更多还原
