The hydro-pneumatic suspension of special vehicles is mainly used to transmit vertical force and ease the impact and vibration caused by uneven road surface. As a new type of elastic element, the Hydro-pneumatic suspension generally uses inert gas or nitrogen as the elastic medium and hydraulic oil as the force transmission medium. Compared with ordinary leaf springs and coil springs, it has the advantages of small size and strong load-bearing capacity. This paper compares the Hydro-pneumatic suspension with hydraulic preload under different conditions and finds that under reasonable parameters, the hydro-pneumatic suspension can provide more stable performance.
