摘要

针对某发动机半主动液压悬置的动态特性及参数影响

基于AMESim多领域仿真平台的理论方法建立了半主动液压悬置模型

模型中考虑了发动机预载对液压悬置腔体内的液体初始压力和解耦膜位置的影响。仿真与试验结果的对比表明:采用所建立的模型对半主动液压悬置的一些重要参数进行参数影响分析

可以获得在ON和OFF状态时动刚度和阻尼角曲线随各参数的变化规律

从而为后期的悬置结构优化奠定良好的基础; 适当增大等效泵压面积、减小橡胶主簧体积刚度及增加惯性通道长度有利于对悬置的低频隔振; 适当增大解耦膜直径有利于对悬置的高频隔振。这些结果可为悬置内部各结构、流体和气体运动以及空气通道开闭实现半主动控制等方面的研究提供参考。

Abstract

To analyze the dynamic characteristics and parameter influence of a semi-active engine hydraulic mount

a model was established on the multi-field simulation platform AMESim. The model considers the effects of engine preload on the initial pressure of the liquid in hydraulic mount cavity and the decoupling membrane position. The comparison between the simulation results and the experimental data shows that the present model can be used to analyze the effects resulting from the important parameters of the hydraulic mount and to obtain the changes of dynamic stiffness and loss angle with each parameter in the ON or OFF state. Properly increasing equivalent pumping area and inertia track length and decreasing rubber stiffness facilitate vibration isolation of the mount at low-frequency

while increasing decoupling membrane diameter facilitates vibration isolation of the mount at high-frequency. This study may be beneficial to the researches on inner structure of mount

movement of fluid and gas

and semi-active control via opening and closing air channel.
