| Abstract: | A novel interconnected hydro-pneumatic spring (IHS) was designed to reduce the impact of
unbalanced loads on static attitude and roll stability of the multi-axle heavy vehicle. The anti-roll function of IHS was analyzed using the principles of hydraulics. The excellent anti-roll characteristic of the proposed IHS was verified by the improved roll stiffness in the simulation. The IHS was mounted on a four-axle heavy vehicle and the experimental results prove the anti-roll characteristic of IHS under static conditions or in turning. |
