Abstract:

The paper used MRF properties for designing MR damping and testing system, a dynamic model for damping system was founded, based on the correspondence between transfer function of continuous system and time series AR model of the discrete system, the dynamic performance parameters,formulas for three-order system were illated.The damping performance and dynamic response of the system were analyzed,in order to find the suitable wording condition for the system.

Key words: MRF(magnetorheological fluid);damping system;AR model, dynamic performance

摘要：

研制了磁流变减振器及测试系统,建立了系统的动力学自回归AR模型。通过连续系统传递函数与离散系统的时间序列AR模型的对应关系推导出了三阶系统动态响应性能参数计算公式,分析了系统的减振性能和系统的动态响应,得到了系统的最优工况。
