TLDR
In this article, the dynamic analysis of a half-car model with a magnetorheological (MR) damper subjected to random excitation has been performed to predict the ride comfort and road holding performance.Abstract:
This 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.read more
