【摘要】 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。更多还原

【Abstract】 The shrill frictional noise of disc brake is investigated . The contact model of frictional surfaces of disc brake is first gived and the effect of contact of rigidity is discussed. The dynamic model of the brake is also gived, the movement equations are set up and its solution is evaluated. On the basis of above-mentioned study, the mechanism and reason of generating frictional noise are analysed. It is proved that the noise is generated by excited self vibration.更多还原
