The Role of Magnetorheological Dampers in Advanced Semi-Active Suspension Systems and their Impact on Vehicle Safety in Automotive Engineering

Abstract

This paper describes a comparative performance analysis of Magnetorheological (MR) dampers and conventional passive dampers. The study aims to describe adaptability and efficacy in vibration control. MR dampers with MR fluids has an advantage of dynamically adjusting their viscosity as per the current response thus enables the damping adjustment and control in real time. This paper describes series of test conducted on MR dampers from 0.5% A, 1.0 A and 2.0 A electric current configurations, generally at higher frequencies, to minimize acceleration as compared to traditional passive damper. The paper represents graphical representations showing frequency and acceleration characteristics and shows the ability of MR damper to optimize and improve vehicle ride and safety. Also, it is observed that MR dampers are a scalable and efficient alternative to conventional dampers, suitable for environments demanding precise and dynamic vibration control.
