| 摘 要： | 通过对电动车刹车噪声机理的研究，验证了自激振动理论。基于刹车盘有限元分析、刹车噪声测量，以及对刹车系统动力学模型的分析与研究表明：刹车盘的高频自激振动引发尖叫摩擦噪声。同时阐明了粘弹阻尼减振降噪原理，提出增加摩擦材料的粘弹阻尼可消除电动车刹车噪声的观点。

| Abstract: | The shrill frictional noise of motor bicycle brake is investigated and the excited-self vibration theory is validated in this paper. It is shown by finite element analysis of disc, testing experiment of braking noise, the frequency spec-trum analysis and study of dynamic model of brake that the noise is generated by excited-self vibration. The theory of using viscoelastic damping materials to reduce vibraton and niose is illuminated and the viewpoint that viscoelastic damping materials can reduce the brake noise of motor bicycle is advanced. |
