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。
The aim of this study is to explore the influence rule of temperature effect on the dynamics properties of magnetorheological damper(MRD).Based on the Bingham mechanical model and the principle of magnetic circuit equivalent,a parametric model of the MRD prototype is established,and ANSYS is utilized to simulate and research influence mechanism and rule of temperature on damping force characteristics,adjustable damping force coefficient and response time.A temperaturedynamics measurement and control test platform for MRD was built.We have carried out experiments on the influence of temperature effect on MRD dynamic performance under different input currents,excitation frequencies and amplitudes,and analyzed the dynamic changes of damping force-displacement characteristics,adjustable coefficients and response time.The result shows that the influence of temperature on the damping force and response time is negatively correlated,and the influence of temperature on the adjustable coefficient is positively correlated.The results of simulation and experiment are well consistent.The results have reference value for the temperature compensation design and performance optimization of MRD.
