摘要：

In this study, one type of magnetorheological fluid dampers (MRD) used in tracked vehicle is chosen as a research object. Firstly, the dynamic response process is analyzed and the dynamic response time of MRDs is defined. In this study, we consider that the dynamic response time of MRDs includes four components, i.e. the electrical power response time, the electromagnetic response time, the response time of magnetorheological fluid (MRF) and the structure response time. The electrical power response time is tested and the electromagnetic response process and the electromagnetic response time of the MRD are analyzed through the method 3D magnetic finite element analysis. Lastly, the response time of the MRD used in tracked vehicle in various working conditions is tested by MRD response time testing system. With the comparison between testing data and analysis of the electromagnetic response process, we can conclude that the structure response time and the electromagnetic response time occupy the largest proportions of the dynamic response time of the MRD and the feasible methods to shorten the response time is to increase rigidity of the MRD system and reduce the eddy effect.
