摘　　要：介绍了基于天棚控制理论的半主动减振器原理,以CRH380A动车组头车为研究对象,对天棚阻尼系数和时滞对车辆动力学性能的影响进行了仿真分析。结果表明:天棚阻尼系数越大,车体横向减振性能越优,但系统允许的最大时滞减小;天棚阻尼系数的设计要同时考虑横向振动性能和系统时滞的影响。半主动控制模式比被动模式对车体横向振动的改善效果均比较明显,平均改善率超过20%。A semi-active damper principle based on sky-hook theory was described. Taking CRH380A EMUs head car as studying object, influence of sky-hook damping coefficient and time delay of the system on the vehicle dynamics performance was analyzed. The results showed that： the greater the sky-hook damping coefficient was, the better lateral vibration performance of vehicle was, and the biggest system allowable time delay turned smaller. So, lateral vibration performance and system time-delay influence should be considered at the meantime for design of sky-hook damping coefficient. Compared with the passive suspension, the semi-active suspension improved lateral vibration isolated performance of car body obviously, the average improvement rate of which was more than 20%.
