Vibration Control in Quarter-Car Model with Magnetorheological (MR) Dampers Using Bingham Model

Sharma S

A semi-active suspension system using Magnetorheological (MR) damper overcomes all the inherent limits of passive and active suspension systems and combines the advantages of both. This paper gives a concise introduction about the suspension system of passenger vehicle which is presented along with the analysis of semiactive suspension system using MR dampers based on Bingham model. Magneto rheological (MR) dampers are filled with magnetorheological fluids whose properties can be controlled by applying voltage signal. To further prove the statement, a quarter car models with two degrees of freedom has been used for modelling the suspension system, the sprung mass acceleration of passive suspension system has been compared with the semi-active suspension system using Bingham model for MR damper. Simulink/MATLAB is used to carry out the simulation. The results drawn show that the semi-active suspension system performed better than the passive suspension system in terms of vehicle stability.
