摘　　要：根据磁流变液的流变特性以及普通液压悬置的结构,设计了一种新型磁流变悬置,并采用Ansoft Maxwell软件对其磁路结构进行分析。利用Matlab/Simulink建立了磁流变悬置系统的仿真模型。为验证SOA优化PID控制的实际效果,与磁流变悬置系统采用PID控制进行比较。怠速工况下的车身俯仰角加速度的峰值和均方根值降低了3.38%和27.15%,车身垂向加速度的峰值和均方根值降低了16.33%和9.85%;行驶工况下的车身俯仰角加速度的峰值和均方根值降低了36.48%和47.55%,车身垂向加速度的峰值和均方根值降低了31.53%和41.45%。分析结果表明,磁流变悬置系统采用基于SOA优化PID控制具有良好的隔振效果。According to the rheological properties of magnetorheological(MR)fluids and the structure of common hydraulic mounts,a new type of MR mount was designed and its magnetic circuit structure was analyzed by Ansoft Maxwell software. The simulation model of MR mounting system was established by using Matlab/Simulink. To verify the actual effect of PID control optimized by SOA,it is compared with MR mounting system using PID control.The peak and root mean square values of body pitch angular acceleration at idle speed were reduced by 3.38% and 27.15%,and the peak and root mean square values of body vertical acceleration were reduced by 16.33% and 9.85%;The peak and root mean square values of body pitch angular acceleration under driving conditions were reduced by 36.48% and 47.55%,and the peak and root mean square values of body vertical acceleration were reduced by 31.53% and 41.45%.The analysis results show that the MR mounting system has a good vibration isolation effect by using the SAO optimized PID control.
