动力总成悬置系统参数识别的功率谱法

动力总成悬置系统的动力学参数是研究悬置系统动力特性和隔振设计的重要依据。提出了一种悬置系统参数识别的方法，即功率谱法，并针对一具体的动力总成悬置系统进行了参数识别。通过实验证明此方法是一种可行的、识别精度较高的有效方法。

Dynamic parameter of power unit mounting system is an important basis for re-searching dynamic characteristic and vibration isolation design of the mounting system. A parame-ter identification method,i. e. power spectrum method,has been recommended and parameter iden-tification process carried out for a practical power unit mounting system- The experiment revealsthat the method is a feasible and effective method with higher accuracy identification.
