Simulation and Test of Influence of Temperature Effect on Dynamic Performance of MRD

  • 摘要: 探究一种温度效应对磁流变减振器(MRD)阻尼动力学性能的影响规律。基于Bingham力学模型和磁路等效原理,建立MRD样机的参数化模型,利用ANSYS仿真研究温度对MRD阻尼力特性、可调系数和响应时间的影响机理和规律;搭建MRD温度-动力学测控试验平台,开展不同输入电流、激振频率和振幅下温度效应对MRD动力学性能影响的试验,分析研究阻尼力-位移特性、可调系数及响应时间的动态变化规律。结果表明:温度对阻尼力和响应时间的影响呈负相关,对可调系数的影响呈正相关,仿真与试验结果保持一致。研究结果对MRD的温度补偿设计和性能优化具有参考价值。
