System Identification of Magnetorheological Damper for Various Configurations

Abstract

A symmetrical Bouc Wen hysteretic model has been proposed for different configuration of MR damper in this paper. The various configurations of the MR damper include varying the annular gap between the cylinder and the piston, the amount of carbonyl iron particles present in the carrier fluid and varying the current. The symmetrical Bouc Wen model is simulated using the MATLAB software and the experimental and simulated force, displacement values are compared, and the maximum damping force is found among the various parameters considered. It is found that the maximum damping force was obtained for 1mm annular gap and a fluid configuration of 80% carbonyl iron particles when excited at a frequency of 0.5Hz with 2.5A power supply.
