摘　　要：基于磁流变液的Bingham模型,提出一种应用有限元法对旋转式磁流变阻尼器进行优化设计的方法,通过对阻尼器的结构参数进行优化设计,可以充分发挥材料磁性能,从而获得阻尼器的最优电气参数。研制磁流变阻尼器及其力学性能测试系统,对阻尼器的力学性能进行试验研究,得到了阻尼器的力矩—转速、屈服力矩—电流等力学特性。考虑温度对磁流变阻尼器性能的影响,得到不同温度、不同转速下阻尼器的屈服力矩特性,对磁流变液剪切变稀现象及温度对磁流变阻尼器性能的影响进行分析。Based on the Bingham model of the magnetorheological fluid, a f＇mite element optimization design method of the rotary magnetorheological damper is presented, In this method, the magnetic permeability of magnetic material is brought into full play by optimizing the structure parameters of damper, so that the optimum electric parameters are obtained. The magnetorheological damper and the mechanic performance test system are developed to research the mechanic performance of the magnetorheological damper, and the damper properties： torque vs speed and yield torque vs current are obtained. What＇s more, the temperature change is considered as one of influence factors on magnetorheological damper performance, and the properties of the damper yield torque at different temperatures and different speeds are obtained. The influence of the magnetorheological fluid shear thinning and temperature change on magnetorheological damper performance are analyzed.
