镁合金是比重最轻的结构材料，具有高的比强度、比刚度和良好的磁屏蔽性、阻尼性、切削加工性等优点。
As the lightest constructional material, magnesium alloy has high specific strength, high specific stiffness, good magnetic-shielding ability, good damping ability, and good machinability.
基于磁流变减振器的汽车悬架系统具有明显的滞后非线性，系统中的非线性阻尼和非线性刚度等对其动力学行为产生了很大的影响。
The automotive suspension system based on magnetic-rheology absorber has obvious lag non-linear, the non-linear damp and non-linear rigidity etc in the system have great effect on dynamics.
但同其它常规流体阻尼器类似，在高频振动时会出现刚度硬化现象，使高频传递率增大，常规磁流变阻尼器多应用于较低频域的振动控制。
But common MR damper cant be used in cases of high-frequency vibrations because of stiffness hardening, which leads to increase of displacement transmissibility at high frequencies.
