提出了一种基于改进天钩阻尼（MSD）控制的重型卡车悬架系统多目标优化策略，同时提高了乘坐舒适性和道路友好性。采用功能虚拟样机技术建立了四轴重型汽车-路面耦合系统模型，并通过平顺性试验对模型进行了验证。考虑阻尼器的力学特性和时滞，利用Matlab/Simulink实现了主动和半主动阻尼器的MSD控制。通过亚当斯和Matlab联合仿真，分析比较了被动、半主动和主动MSD控制的效果，从而选择了综合性能最好的控制参数。仿真结果表明，MSD控制改善了卡车的乘坐舒适性和道路友好性，而半主动MSD控制阻尼器获得的道路友好性与主动MSD控制阻尼器相当。
This paper presents a multi-objective optimization strategy for heavy truck suspension systems based on modified skyhook damping (MSD) control, which improves ride comfort and road-friendliness simultaneously. A four-axle heavy truck-road coupling system model was established using functional virtual prototype technology; the model was then validated through a ride comfort test. As the mechanical properties and time lag of dampers were taken into account, MSD control of active and semi-active dampers was implemented using Matlab/Simulink. Through co-simulations with Adams and Matlab, the effects of passive, semi-active MSD control, and active MSD control were analyzed and compared; thus, control parameters which afforded the best integrated performance were chosen. Simulation results indicated that MSD control improves a truck’s ride comfort and roadfriendliness, while the semi-active MSD control damper obtains road-friendliness comparable to the active MSD control damper.
