%X Hydro-pneumatic suspension is widely used in heavy vehicles due to its nonlinear characteristics of stiffness and damping. However, the conventional passive hydro-pneumatic suspension can</span><span style=\"font-family:Verdana;\">กฏ</span><span style=\"font-family:Verdana;\">t adjust parameters according to the complicated road environment of heavy vehicles to fulfill the requirements of the vehicle ride comfort. In this paper, a semi-active hydro-pneumatic suspension system based on the electro-hydraulic proportional valve control is proposed, and fuzzy control is used as the control strategy to adjust the&nbsp;damping force of the semi-active hydro-pneumatic suspension. A 1/4&nbsp;semi-active hydro-pneumatic suspension model is established, which is co-si</span><span style=\"font-family:Verdana;\">mulated with AMESim and MATLAB/Simulink. The co-simulation results show that the semi-active hydro-pneumatic suspension system can significantly reduce vibration of the vehicle body, and improve the suspension performance comparing with passive hydro-pneumatic suspension.
