摘　　要：在ADAMS中建立了油气消扭悬架系统的机械及液压模型,进行了消扭工况仿真并将其与试验数据进行了对比分析,验证了所建油气消扭悬架系统模型的正确性。利用建立的整车模型对油气消扭悬架汽车的性能作出了预测,结果表明,消扭悬架不会破坏汽车的操纵稳定性,且在减小车身的扭矩、轮荷偏载及保证车轮与地面的良好附着方面效果明显。A mechanical and hydraulic model of the hydro-pneumatic torsion eliminating suspension was established in ADAMS. The torsion eliminating conditions were simulated and compared with the test data to validate the established model of hydro-pneumatic torsion eliminating suspension performance of the vehicle with the hydro-pneumatic torsion eliminating suspension was the established vehicle model. It was proved that the torsion eliminating suspension eliminating the vehicle body twist load, decreasing the unbalance of the tire vertical loads the good contact between tire and road without negative effects on the vehicle handling s system. The predicted by is good for and ensuring tabilily.
