COMPARATIVE STUDY AND ANALYSIS OF AUTOMOTIVE SUSPENSIONS SYSTEM

Abdul Rehman Ahmad

Abstract


The purpose of this paper is to compare the Double Wishbone Leaf spring suspension system and the Macpherson Suspension system. On these suspension systems, ANSYS is used to achieve the goal of static structural analysis. Static loads are applied to the suspension system. The analyses, including structural analysis with static loading, to analyze the deflection, stress, and strain of the suspension systems, thorough which a complete comparative study can be accomplished.

A MATLAB Simulink block diagram was developed for the analysis. The algorithm developed here can be used to analyze an automobile's quarter car model using 2DOF, saving money on the circuit and rig testing.

Vibrations induced by road disturbances are not conveyed to the driver by automotive suspension systems. To simulate this a quarter vehicle model with two degrees of freedom (DOF) is produced. The impact of a speed bump as a step function is examined for the overshoot and settling time of sprung mass. A sine function is also used to replicate the characteristics of a bumpy road surface
