| 摘 要： | 分别建立了车辆-轨道-桥梁系统的垂向耦合振动模型和空间耦合振动模型，并通过功率普密度得到轨道高低不平顺的时域模拟样本，以其作为激励，分析两种模型下车辆-轨道-桥梁耦合振动系统的振动响应。通过对比相同轨道高低不平顺激励下垂向振动模型和空间振动模型的垂向振动响应计算结果，分析了两种模型的优缺点和适用性。

| Abstract: | In this paper, models for vertical and spatial coupled vibration of vehicle-track-bridge system are established seperately. The track vertical irregularity smaple in time domain was established by power spetrum density and taken as the exciting source to analyze the coupling vibration of vehicle-track-bridge system of two models. The advantages, disadvantages, the applicability of the vertical vibration model and the spatial vibration model were analyzed by comparing the vertical vibration responses of the two models under the excitation with same level of track vertical irregularity. |
