Design and Simulation of Automotive Suspension System for Different Values of Damping

The main aim of this paper is to simulate and analyze the passive suspension system for quarter car model with variable damping values. The main purpose is to provide background for mathematical model of a quarter-car model. Ride Comfort (RC) are important concern related to vehicle suspension system. The disturbances are mostly in the form of various road profiles that the unsprung mass comes in direct contact with and are transmitted to the sprung mass causing undesirable vibration that may cause discomfort to passenger. The purpose of mathematical modeling is to obtain state space representation of the quarter car model. In this project, analysis of vehicle suspension using Quarter-car model developed in MATLAB SIMULINK. The initial mathematical model is developed and the analytical results are taken on Matlab as an analytical solver. In later stages the experimental setup is developed and the actual readings are taken for various inputs (damping values); finally both experimental and analytical results are compared for ride comfort and reliability of experimental setup.
