The last part concludes that mr dampers is one of the very attractive control elements in semi - active control . as one of mixed model mr dampers , armature piston ' s mr dampers have principle designs good function and better practical value , it ' s worth to popularize use . about the armature piston ' s mr damper ' s designs , the space of work , the diameter of wok and the length of magnetic pole have obvious affects to the force of mr dampers , mr fluid materials should be paid attention , input electric current affects mr dampers greatly the high current increases the damping force , the effect of reduce vibration increase obviously , 最后，论文给出了结伦：磁流变液阻尼器是半主动控制装置中非常吸引人的控制元件之一，混合工作模式的磁流变阻尼器结构简单，阻尼效果比流动模式和剪切模式均要好，是一种比较理想的磁流变阻尼器；电枢活塞式磁流变阻尼器作为混合模式磁流变阻尼器的一种结构形式，其结构设计合理，性能良好，具有较强的实用价值，值得在工程中推广应用；在电枢活塞式磁流变阻尼器的设计中，应特别注意工作间隙h 、工作直径d 、磁极长度卜都对阻尼器的阻尼力有明显的影响，并注意选用合适的磁流变液材料；输入电流对磁流变阻尼器的阻尼效果影响很大，输入大电流时阻尼力明显增大，减振效果明显提高。
