摘　　要：由于共振,当火车运行到某一速度时会发生强振,发出“咣当”噪声.根据力学原理,采用在车轮与因厢之间加橡胶垫的方法,改变支持系统的弹性系数,可以消除火车“咣当”噪声.Because of resonance,when the train moves at the speed of VO,it acn make the strong shock, send out clickety clack noise. According to mechanics principle, adding the tubber packing between the wheel and the carriage compartment can change the elasticity coefficient of strut system, inthis way, it may eliminate the train clickety clack noise.
