摘要:为了实现汽车减振效果实时可调,提高驾乘舒适性,采用了一种新型智能材料—磁流变弹性体(MRE)作为汽车悬架系统的核心材料,运用Matlab Simulink软件建立了汽车减振系统仿真模型,并相应建立了实验装置,通过计算获得了该系统模型在不同磁场下的等效阻尼和等效刚度,对其减振效果进行了仿真和实验分析。研究结果表明,磁流变弹性体应用于汽车减振系统有效并可以实现减振效果可调。

Abstract: Aiming at realizing the automotives vibration reduction capability to be nonadjustable to varying road conditions and the comfortableness of the drivers and passengers, a new smart material namely magnetorheological elastomer (MRE) was attempted for the automotive vibration reduction system. A simulation model was created based on Matlab Simulink software and a test rig was also developed. The model was used to calculate the equivalent stiffness and damping properties of the system under different magnetic field strength. Further on, the vibration reduction effect of the system was studied through both simulation analysis and experimental verification. The study result shows that it is effective to apply MRE for automotive vibration reduction and the effect of such a vibration reduction system can be adjusted.
Key words: automotive vibration reduction; magnetorheological elastomer(MRE); simulation study; equivalent damping; equivalent stiffness
