Abstract

In this paper, the response time of one magnetorheological fluid (MR) damper with maximum damping force of 250kN was tested. Experimental results show that, when electric current increase, response time is about 0.1 to 0.3s; when current decrease and not to zero, response time is about 0.2 to 0.3s, higher change of current induce longer of response time. Experimental results also show that, when electric current decrease to zero, response time is about 0.6 to 0.7s, which is much longer than expected. Further experiment results show that, if subtracting response of coil, when current increase, the response time is about 60 to 70ms, when current decrease and not to zero, the response time is about 140 to 150ms.
