Hydro-Pneumatic Passive Suspension System Performance Analysis using AMESim Software

Abstract

In this research, a mathematical model of quarter car hydro-pneumatic suspension system is built and developed using the AMESim software. The influence of hydro-pneumatic suspension system performance on the suspension parameters is presented on random road surface. The comparisons between passive and hydro-pneumatic suspension system is plotted. The result showed that the hydro­ pneumatic suspension system acceleration is reduced by 50%, 12% reduction in suspension working space and 3% reduction in dynamic tyre deflection in comparison with the traditional passive suspension system.
