A Review of half-car model vibration system using Magneto rheological Dampers

Abstract

The suspension system is very crucial when considering the ride comfort of vehicle driver and passengers. Most of the research these days is based on the use of semi- active suspensions for vehicle suspension system. This system having a semi- active suspension with MR dampers is promising way of improving the ride comfort. This paper reviews the various ways of improving the ride comfort using various mathematical models, experimental work and gives an overall conclusion of why using a semi- active suspension system with MR dampers is better than using a passive system or an active system. Half-car model with MR dampers using Modified Bouc-Wen model and RNN control improves ride comfort. Damping coefficient limit of 4000 N·s/m is optimal. Semi-active suspension outperforms passive systems. The semi-active suspension system is reviewed and the following important conclusions are noted. The control methods viz. the R-S control and the MSK control method have more vibration control capabilities than by applying a constant current/voltage to the MR damper of the system. Hence, these control methods are preferred over the methods which use constant current/voltage.
