Hemanth, K.Kumar, H.Gangadharan, K.V.2020-03-312020-03-312018International Journal of Acoustics and Vibrations, 2018, Vol.23, 2, pp.138-146https://idr.nitk.ac.in/handle/123456789/10656This paper presents the dynamic analysis of a half-car model with a magnetorheological (MR) damper subjected to random excitation. Experimental studies have been conducted to predict the behavior of the prototype twin-tube MR damper. The mathematical model of the prototype MR damper has been proposed by using the Bouc-Wen model. The half-car model with the MR damper has been used to predict the ride comfort and road holding performance. Comparative studies between the half-car model with the passive and semi-active suspension system with a proportional-integral-derivative (PID) control shows that the MR damper suspension system offers a good performance. 2018 International Institute of Acoustics and Vibrations.
