Pdf An Approximate Method For The Evaluation Of The Roll Stiffness Of Road Tankers Anti-Roll Bar Stiffness - U-Bar For calculating the stiffness of a typical U-style anti-roll bar. For balancing the force acting on the anti-roll bar mounting point is then calculated according to the chosen motion ratio for the anti-roll bar. 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. 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.
