摘要

摘要: 探讨应用动态特性特征点法预测与识别液阻悬置集总参数模型主要参数的分析方法。该方法首先通过实验来得出液阻悬置动态特性特征点,运用傅里叶变换的方法对液压悬置的集总参数模型进行深入推导得到液压悬置的复刚度,然后通过建立的动态特性特征点与集总参数之间的关系求解得出集总参数的值。通过对数值预测结果与实测结果对比分析表明,基于动态特性特征点法的液阻悬置集总参数模型动特性分析技术是可行、有效的,其预测结果精确性满足工程要求。

Abstract: Characteristic feature point methods and computational fluid dynamics(CFD) methods were applied to prediction or identification of the model parameter. The dynamic characteristic feature points were obtained with testing dynamic characteristics of the hydraulically damped rubber mount(HDRM) firstly and the complex stiffness of hydraulically damped rubber mount was derived from lumped parameters(LP) model by Fourier transform, and then the LP model was calculated by the relation developed between the feature points and the lumped parameters. The results were compared with experimental data,the work conducted in the paper demonstrates that the method for estimating the system parameters in the LP model of HDRM is effective.
