| 摘 要： | 利用车—桥耦合计算模型,从静力和动力两个方面分析了27t轴重货车在既有线运行时车辆和桥梁的耦合响应特性进行了分析。结果表明27t轴重货车具有较好的动力学性能;在充分考虑车辆运行状态和桥梁安全储备的基础上,需对既有桥梁,特别是小跨度桥梁等设备状态进行必要的评估和监测,以确保27t轴重货车开行的安全性。

| Abstract: | The vehicle-bridge coupling response characteristic of the wagon with 27 t axle load running on the existing railway lines was analyzed from two aspects of static and dynamic.The results show that the wagon with 27 t axle load has good dynamics performance;the condition of bridge must be evaluated and monitored based on the running estate of train and safety reserve of bridge in order to ensure the best safety,especially for the small span bridge. |

| Keywords: | vehicle-bridge coupling dynamic response evaluate safety |
