根据空气弹簧刚度试验，建立了1/2汽车垂向振动模型。进而，依据天棚控制和地棚控制特点，设计了汽车磁流变减振器半主动空气悬架综合控制策略。在Matlab/Simulink环境下对带有不同控制策略的悬架系统进行性能仿真。对比时、频域仿真结果表明：采用综合控制策略不仅能提高汽车平顺性，且能保证汽车的操纵稳定性，使车辆综合性能得到改善。
根據空氣彈簧剛度試驗，建立瞭1/2汽車垂嚮振動模型。進而，依據天棚控製和地棚控製特點，設計瞭汽車磁流變減振器半主動空氣懸架綜閤控製策略。在Matlab/Simulink環境下對帶有不同控製策略的懸架繫統進行性能倣真。對比時、頻域倣真結果錶明：採用綜閤控製策略不僅能提高汽車平順性，且能保證汽車的操縱穩定性，使車輛綜閤性能得到改善。

Based on the stiffness test of air spring, a half vehicle vertical vibration model is established. Then, according to the characteristics of skyhook control and groundhook control, a combined control strategy for semi-active air suspension with magneto-rheological ( MR) damper is designed. The performances of suspension sys-tems with different control strategies are simulated with Matlab/Simulink. The comparison on the results of simula-tions in both time and frequency domains show that with combined control strategy, not only the ride comfort of vehi-cle can be enhanced, but also the handling stability of vehicle can be ensured, leading to the improvement of overall performance of vehicle.
