This research delves into how the design elements of hydro-pneumatic suspension systems (HPSS) impact the comfort of the ride, focusing on a particular brand of off-road vehicle. The suspension system was engineered, and its mathematical representation was formulated. The study explored the effects of varying the accumulator’s initial pressure and the size of the throttle valve opening on the system’s stiffness and damping properties. A dynamic simulation of the HPSS was developed using MATLAB-Simulink. By adjusting the damping forces to adapt to different terrains, significant enhancements in vehicle performance and comfort were realized. This methodical tuning not only boosts the stability of the drive but also reduces the disturbance caused by uneven road surfaces on the vehicle’s dynamics. The results highlight the significance of refining damping force management to optimize both the vehicle’s handling and the comfort of its passengers in practical driving conditions.
