摘要
液压悬置是一种先进的减振系统,其动态特性对汽车的乘坐舒适性和NVH性能有很人影响。但是液压悬置的动态特性非常复杂,既具有频变特性,又具有非线性特性。本文基于系统辨识及数值分析理论,提出了模拟液压悬置动态特性的一种数值拟合方法。
Hydraulic mount system is one of the advanced damping systems. Its dynamic characteristic has a great effect on ride comfort of motor vehicles. But the hydraulic mount has a complicated dynamic characteristic with frequency dependence and non-linearity. Based on system recognition and numerical analysis theory, a numerical fitting method had been put forward in this paper.
