Abstract

This study presents a seven degree of freedom, dynamic model for a two-axle vehicle which is used to analyse the influence of road profile on the vehicle's rollover capabilities and ride characteristics. Non-linear elements are included due to the air suspension featured in the vehicle. Road roughness is represented as a Power Spectral Density (PSD) function acting as an exciting force on the unsprung masses of the seven degree of freedom model, and solved numerically for both rollover simulation and lane change manoeuvre. Results indicate that road surface does have a significant impact in a vehicle's performance since it may prompt the vehicle to flip over below its rollover threshold.
