Abstract
This paper describes a hydraulic suspension which is shown by simulation to give lower body accelerations and lower dynamic tyre forces than a conventional suspension.
Eigenvalue analysis is used to help explain how the advanced system simulates an active suspension, operating with a “sky-hook” damper control strategy. A 3-dimensional mathematical model is used to explore the performance of the advanced system. Comparisons with a conventional suspension showed that the advanced system offers 30% lower ISO weighted, root mean square body vertical acceleration and 10% lower root mean square dynamic tyre forces.
