Suspension roll angle is one of the key factors affecting a vehicle's static roll stability, and also an important influencing factor for other performance indicators such as steering angle, neutral steer point, and lateral acceleration.
To increase the suspension's roll stiffness, modern vehicles are typically equipped with anti-roll bars. When designing anti-roll bars, two directly related design indicators need to be considered: the equivalent roll stiffness at the wheel and the anti-roll bar's own roll stiffness. Furthermore, the anti-roll bar's design must meet strength requirements and its mass should be reduced as much as possible.
