汽车盘式制动器制动尖叫的分析

针对某轿车盘式制动器的制动尖叫问题,在实体模型的基础上建立了制动器各主要部件的有限元分析模型和耦合接触模型。为了提高模型的计算精度,采用模态实验对有限元模型参数进行了修正。通过振动测试方法对盘式制动器进行振动噪声测试,获得了制动器及其主要部件的振动信号和噪声

Brake Squeal Analysis on Disc Brake Squeal

According to the problem of disc brake squeal of one car,on the basis of the model in the entity the finite element model and coupling contact model were established.For improving the calculation precision of the model,finite element model parameters were modified by utilizing modal experiment.Vibration signal and noise signal from brake and its main parts were obtained by testing vibration and noise from disc brake.The cause of disc brake squeal was obtained by comparing the experimental results with the f...
