摘要： 基于技术的发展趋势，对越野机动性提出更高要求，需提升悬架性能以满足整车性能 要求，因此，提出一种可应用于螺旋弹簧与油气弹簧的阻尼可调磁流变减振器的技术方法。 搭建了 AMESim 与 MATLAB 联合仿真的半主动悬架系统模型，采用线性混合天棚控制算法 控制磁流变减振器。结果表明，在 F 级、车速 30 km/h 的随机路面上，半主动螺旋弹簧相比 被动螺旋弹簧，其平顺性提升 28.3%；半主动油气弹簧相比被动互连式油气弹簧，其平顺性 提升 48.1%。在 B 级、车速 60 km/h 的随机路面上，半主动螺旋弹簧相比被动螺旋弹簧，其 平顺性提升 50%；半主动油气弹簧相比被动互连式油气弹簧，其平顺性提升 66.7%。所提阻 尼可调磁流变减振器的技术方法在不同随机路面上显著提高多轴越野车辆的平顺性，为后期 半主动悬架系统在多轴重型车辆中的应用提供仿真依据。

Abstract: Based on the current development trend of technology, higher requirements are placed on off-road mobility, and suspension performance needs to be improved to meet the vehicle performance requirements. Therefore, a technical method of damping-adjustable magnetorheological damper applicable to both coil springs and hydro-pneumatic springs is proposed. A semi-active suspension system model is established through AMESim-MATLAB co-simulation, and the linear hybrid skyhook control algorithm is adopted to control the magnetorheological damper. The results show that on F-class random road at a vehicle speed of 30 km/h, the ride comfort of the semi-active coil spring suspension is improved by 28.3% compared with the passive coil spring suspension, and that of the semi-active hydro-pneumatic spring suspension is improved by 48.1% compared with the passive interconnected hydro-pneumatic spring suspension. On B-class random road at a vehicle speed of 60 km/h, the ride comfort of the semi-active coil spring suspension is improved by 50% compared with the passive coil spring suspension, and that of the semi-active hydro-pneumatic spring suspension is improved by 66.7% compared with the passive interconnected hydro-pneumatic spring suspension. The proposed technical method of damping-adjustable magnetorheological damper significantly improves the ride comfort of multi-axle off-road vehicles on different random roads, providing a simulation basis for the subsequent application of semi-active suspension systems in multi-axle heavy vehicles.
