摘　　要：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。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-theological （MR） damper is designed. The performances of suspension systems 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 vehicle can be enhanced, but also the handling stability of vehicle can be ensured, leading to the improvement of overall performance of vehicle.
