Abstract: This paper presents a multi-objective optimisation strategy for heavy truck suspension systems based on Modified Skyhook Damping (MSD) control, which improves ride comfort and road-friendliness simultaneously. A four-axle heavy truck–road coupling system model was established; the model was then validated with a ride comfort test. Through co-simulations with Adams and Matlab, the effects of passive, semi-active MSD control and active MSD control were analysed and compared. Simulation results indicated that MSD control improves a truck|s ride comfort and road-friendliness, while the semi-active MSD control damper obtains road-friendliness comparable with that of the active MSD control damper.

Keywords: MSD control; heavy trucks; heavy vehicles; vehicle suspensions; suspension optimisation; ride comfort; road damage; skyhook damping control; road friendliness; modelling; modified SDC; simulation; semi-active control.
