The anti-roll bar is an important element of the suspension since it allows the designer to control the roll stiffness of the vehicle independently from the bump stiffness. So the anti-roll bar system design analysis and manufacturing for a formula student race car is a not well-studied topic with the help of this particular study and we aim to develop tunable anti-roll bar devices for individual axles for a Formula student race car.

The anti-roll bar cantilever length measured from the centre line of the roll bar to where the canti-lever mounts to the drop link. The Anti-roll bar must be installed via a rubber bush 2 which restricts the degree of freedom and allows only rotation along the axis of the anti-roll bar. The anti-roll bar is an important element of the suspension since it allows the designer to control the roll stiffness of the vehicle independently from the bump stiffness. As a result the outer wheel moves up with respect to the chassis and the inner wheel will move down.
The size was determined by comparing the required area moment of inertial to the area moment of inertia of the arb system torsion bar with desired dimensions.
