【摘要】 在JF 1 32型汽车制动器试验台上进行了AUDI盘式制动器的动态测试 ,建立了该制动器的带外生变量的自回归 (ARX)模型。根据试验中获得的数据 ,确定了模型的结构 ,采用最优辅助变量法对所建模型的参数进行了辨识 ,通过残差白色性检验以及不同观测数据的比较 ,验证了所建模型的精确程度。更多还原

【Abstract】 Dynamic test of AUDI disc brake was performed on JF 132 vehicle brake tester.ARX model with external variable of the brake was developed.Based on measured data,model structure was determined,model parameter was identified employing optimal auxiliary variable method.Through validation of residual whiteness and comparison of different observed data,precision of model was confirmed.更多还原
