| 摘 要： | 车桥振动问题是车辆和桥梁两个动力系统耦合振动问题，为掌握桥梁结构动力响应特性，必须研究不同车辆模型对桥梁结构动力响应的影响。基于车桥耦合振动原理，采用Matlab语言编制车桥耦合振动专用程序。采用该程序对一座简支梁桥的动力响应进行分析，对不同车辆模型作用下的计算结果进行比较，结果表明不同车辆模型对桥梁的动力响应存在差异，且对不同动力响应的影响程度也不同。

| Abstract: | The vibration problem of the bridge structure under the vehicles loading action is a coupling vibration problem of the vehicle system and bridge system.In order to grip the dynamic characteristic of bridge structure,it is necessary to analyze the related different vehicle models.Based on the principle of vehicle-bridge coupling vibration,a program for vehicle-bridge coupling vibration analysis is developed using the Matlab programming language in this paper.An analysis is made on a simple supported beam and... |
