Abstract：Taking the semi-active air suspension system of a novel adjustable damping as research object, the whole vehicle dynamic model of air suspension system was established based on the structures and working mechanism.Variable structure control system of vehicle semiactive air suspension damping was designed based on model-tracking, and D2P rapid development platform was applied to design quasisliding mode variable structure controller. The test bench of semi-physical model was established based on MTS320 road simulator to investigate vehicle ride performance. The simulation and test results show that the sprung mass acceleration root mean square is decreased by 19.34% than that under ″allvalve closed″ damping condition, and increased by 2.65% than that under ″allvalve opened″ damping condition after control. The front and the rear suspension dynamic deflection root mean squares are respectively increased by 33.00% and 10.00% than those under ″all-valve closed″ damping condition separately, and decreased by 12.50% and 8.33% than those under ″allvalve opened″ damping condition. The vehicle ride performance and riding comfortable performance are effectively improved by the proposed quasi-sliding mode variable structure damping control system of semi-active air suspension.
