摘　　要：为探讨简单实用的磁流变减振器动力学性能模型,根据磁流变减振器的动力学性能试验结果,基于MATLAB分别针对修正后Bingham模型的系数和修正后Dahl模型的系数进行参数辨识,并用另一组试验数据对辨识结果进行了验证及对比。结果表明,此方法简化了磁流变减振器模型参数辨识,而且还可用于其他非线性动力学模型的参数辨识。In order to explore the simple and practical dynamic performance model of the magnetorheological damper,parameters of the modified Bingham model and the modified Dahl model were identified by employing MATLAB,according to the experimental results of its dynamic performance,and the identification results were verified and compared with another set of experimental data.The results show that the proposed method has simplified the parameter identification process of magnetorheological damper model, which can also be used for parameter identification of other nonlinear dynamic models.
