Duhamel积分在车辆振动中的应用

Application of Duhamel Integral on Vehicle Vibration

从二自由度系统的动力学模型出发,求出主体冲击响应,并以这个响应作为输入用Duhamel积分求出隔振器变形响应,给出了一种新的解决二自由度振动问题的方法,结果表明Duhamel积分法在保证设计安全性同时又能准确地求出隔振器最大变形,为隔振器设计和选型提供理论依据。

Impact response of main body is obtained from a dynamical model of binary degree of freedom system , which serves as input. Distortion response of vibration isolator can be calculated through Duhamel intergral. It shows a new method to solve vibration problem of binary degree of freedom. Results show that Duhamel intergral can ensure design security as well as accuracy to calculate maximum detortion of vibration isolator, which supplies theoretical basis to design and type selection of vibration isolator
