摘要
探讨高速列车在轨道结构上运行时的垂向耦合振动问题是列车-轨道耦合动力学更深入的理论研究。本文建立了铰接式高速列车-轨道垂向耦合动力学模型及方程,运用新型快速数值积分方法编制了这一大型系统的动力学仿真程序,对铰接式高速列车垂向动力学性能,特别是车辆与车辆之间的耦合振动以及车辆与轨道之间的动力作用进行了系统仿真分析,并与非铰接式高速列车进行了比较。结果表明。
This paper presents the study of vertical coupling vibrations of high speed trains running on the track structures.A dynamic model is developed to investigate the vertical interactions between the high speed articulated trains and tracks.The equations of motion of the articulated train are derived.A simulation program is designed for such a large scale dynamic system by use of a new fast integration method.The vertical dynamic performance of the high speed articulated train is analyzed,especially focusing on the coupling vibration between neighbouring vehicles and on the dynamic interaction between vehicles and tracks.By comparing the results of the articulated train and the non articulated train,it could be concluded that the high speed articulated train possess better vertical dynamic performance.
