Magnetichysteresis is the intrinsic characteristic of MR dampers, which will have more serious effect on the performance of MR dampers.
本文对MR阻尼器的固有特性磁滞效应对控制效果的影响进行了研究。

Finally, we study the size effect of hysteresis in the mixed magnetic films. It is found that the step effect and the coercivity are influenced by the size of the mixed magnetic films greatly.
