In order to analyze the ride performance on a mining truck using the hydro-pneumatic and rubber suspension systems under different road surface conditions, a dynamic model of a mining dump truck with 7 degrees of freedom is established under random excitation of road surface roughness. The weighted r.m.s acceleration responses at the vehicle body center of gravity in the vertical direction (awb), pitch angle (awphi) and roll angle (awteta) according to ISO 2631-1 are selected as the objective functions. The analysis results showed that the awb, awphi and awteta values with the hydro-pneumatic suspension system decrease respectively compared to the rubber suspension system under surveyed road surface conditions, which means that the ride performance of the mining dump truck with hydro-pneumatic suspension system is significantly improved compared to rubber suspension system when the vehicle moves under different road surface conditions.
