Modal Development and Experimental Study for Dynamic Characteristics of Vehicle's Switchable Engine Mounts
摘要
Abstract
Switchable engine mounts (SEM) play a significant role in the design of High-intermediate level sedans and SUVs.Two kinds of switchable engine mounts with orifice tunable and decoupled stiffness variable,respectively,are introduced in this paper.Lumped parameter models are developed and their key parameters are identified by experiment and genetic algorithm.The dynamic characteristics of both on/off modes are simulated and tested for each mount,agreement between the results of the two methods is achieved.Finally,the sensitivity of parameters was analyzed.The present work can provide some reference for the design,improvement and optimization of SEM.关键词
