Effects of suspension configuration and ride height change on a cornering vehicle

posted on 2024-08-01, 14:12 authored by Bongani ZuluBongani Zulu

The attached data and figures elucidate the impact of various suspension configurations on vehicle dynamics, specifically focusing on roll angle, roll rate, steering angle, and lateral load transfer ratio (LTR). The figures demonstrate how changes in suspension settings, such as ride height adjustments and suspension setups at both the front and rear axles, influence the vehicle's handling characteristics. The roll angle and roll rate figures highlight the vehicle's stability and tendency to roll during manoeuvres, while the steering angle figures show how these suspension adjustments affect the vehicle's responsiveness and directional control. The LTR figures provide insight into the distribution of lateral forces across the tyres, indicating how suspension configurations can mitigate or exacerbate rollover propensity. Collectively, these data and figures underscore the critical role of suspension tuning in enhancing vehicle performance and safety.
