对刹车时发出的尖叫摩擦噪声的机理进行研究。首先分析和给出了摩擦表面的接触模型，进一步给出了刹车装置动力学模型，并进行了求解。在此基础上分析和论证了摩擦噪声产生的机理及规律，表明：尖叫摩擦噪声是由摩擦引发的高频自激振动所致。
The mechanism of screaming frictional noise emitted when braking is studied. First, the contact model of the friction surface is analyzed and given. The dynamic model of the brake device is given and solved. Based on this, the mechanism and rule of friction noise are analyzed and demonstrated. The results show that the friction noise is caused by high-frequency self-excited vibration caused by friction.
