Designing of an Anti Roll Bar to Adjust the Balance and Stability of a Formula Student Car

Abstract

This paper focuses on the designing procedure of an adjustable anti-roll bar (ARB) for a Formula Student Car. ARB is a component in suspension assembly which can provide a specific understeering effect to the vehicle depending on its roll stiffness. Different drivers prefer different understeering effects on the car depending on their driving style. For this project, Adjustability in ARB leads to 4 roll rate distribution and 3 roll gradients in the car hence overall 12 settings from one ARB assembly. The ARB has been designed using software like MATLAB and MS Excel to obtain the geometric dimensions and specific orientation of the ARB blade pertaining to different balance and stability. This paper also demonstrates the effect of ARB on suspension travel. The proposed method can help drivers to choose the vehicle dynamics according to their driving style in different tracks.
