Abstract:

The paper presents the computer simulations and experimental validation on a new active suspension used for vehicle roll control. This study focuses primarily on the dynamics of Hydraulically Interconnected Active Suspensions and the dynamics of a vehicle fitted with the suspension. The proposed active suspension, also called as Demand Dependent Active Suspension, consists of four double direction hydraulic actuators which are hydraulically interconnected, and a pressure controlled fluid supply unit. The suspension can actively tilt the vehicle against its vibration modes (roll, pitch, bounce and articulation), by applying required restoring forces or moments. It therefore far exceeds the capability of passive or semi-active suspensions. This study evaluates the first part of the vehicle multi-mode control based on the proposed active suspension, i.e., implements vehicle roll control. This is because of the dangerous nature and fatal injuries associated with vehicle rollover incidents. Modeling, simulations and preliminary experiment of system dynamics of a vehicle fitted with the proposed suspension are carried out and the obtained simulation results agree with those obtained from experiment.
