Design and Development of Damper for Semi-Active Suspension System

Abstract

Conventional suspension system is specified in terms of viscosity of the damper which can’t be changed. Force transmitted to the damper by the conventional suspension system is slightly high. Varying the properties of the damper according to the force applied can improve the stability of the vehicle. To design and manufacture cost-effective MR fluid damper for semi-active suspension system. In this work, we designed and manufactured an MR Damper, analyzing the damper in ANSYS for different metals/alloys and selecting the final material considering higher magnetic saturation, lower cost involvement and adequate strength of the damper. First, the damper is designed considering a certain amount of load, analyzed for different materials, then magnetic circuit is designed accordingly. This work is focused on optimum vibration mitigation and material selection while keeping costs low.
