摘　　要：应用于车辆上的磁流变液减振器是一种变刚度阻尼系统,它利用磁流变液随磁场快速响应特性,可在不同的磁场强度下改变阻尼值。为此建立了一套磁流体减振器试验系统,通过分析多组实验数据发现可变阻尼减振器在不同的振动工况下都会有一个最优的阻尼值,此时系统的减振效果最好。变刚度阻尼系统用于车辆悬架系统中可以提供更好的乘坐舒适性。The magnetorheological fluid damper applied on the vehicle is a variable stiffness damping system which uses magnetorheological fluid rapid response characteristics to change the damping value under different magnetic field intensity.A set of magnetic fluid shock absorber test system is built for this system.Through analyzing multiple groups experimental data,we found that the variable damping shock absorber will have an optimal damping value under different vibration conditions,which adopted in vehicle suspension system can provide better riding comfort.
