Abstract

Abstract

The coupled vertical model of left and right air springs was considered, a mathematical model of vehicle system was set up, the dynamic equations of air spring were derived from the state equations of ideal gas, and the dynamic performances of vehicle and air spring were simulated when vehicle passed through curve.Simulation result shows that because of the action of leveling valves, the pressures of air springs are different, so that the displacement of car body does not tend to zero after curve negotiation; when vehicle runs along curve at normal speed, its dynamic curving performance varies little; when vehicle passes through the same curve time after time, the pressure's mutative range of air spring is certain; the increase of anti-roll stiffness reduces the roll angle of car body and the pressure change of air spring; the lateral distance increase between air springs and choosing appropriate stiffness and damping of air spring may keep the pressure of air spring tending to its static equilibrium value after vehicle passes through the curve.
