| Engine mounting influence on vehicle comfort, the researchers pay attentions on itin recent years, the suspension vibration isolation performance will directly affect theuser evaluation of vehicle comfort. Magnetorheological suspension using MRFcharacteristics for its continuous, rapid and easily control, therefore the suspension willhave adjustable damping force, and has better vibration isolation effect.This paper mainly in view of the magnetorheological suspension research on thefollowing aspects:1、Expounds the function of the suspension system, the design requirements andideal performance index, according to the vibration characteristics of engine, analysesthe working principle and and working mode of magnetorheological suspension,designs a squeeze mode magnetorheological suspension.2、According to electromagnetic field theory, design magnetorheological suspensionmagnetic circuit, established the finite element model of electromagnetic field ofmagnetic circuit. According to squeeze mode magnetorheological suspension,optimization model is established. Using AMSYS APDL parametric design languageand genetic algorithm, make a structure optimization for the mount.3、Using bond graph theory, established a bond graph model of magnetorheologicalsuspension, deduce its mathematical model. The various main parameters is determined.Using MATLAB simulink software，make a simulation about the suspension.dynamiccharacteristic.4、Manufacturing the magnetorheological suspension test samples, according to thenational standard, use the CRIMS electro-hydraulic servo fatigue testing with differentcurrent, under different frequency, test the dynamic characteristics of suspension andanalyzed the experimental results. |
