| 摘 要： | 通过Universal Mechanism和ANSYS软件相结合建立了车桥耦合振动模型，考虑车型、行车速度、车重和桥梁频率等因素，对工程常用的4种标准跨径装配式混凝土空心板梁桥进行了车桥耦合振动模拟。研究表明:冲击系数随车速增加而上升；随车重增加而增大；随桥梁频率的增加而降低。在多种因素中，车速对冲击系数影响最为明显。

| Abstract: | Through the combination of Universal Mechanism and ANSYS software, the vehicle-bridge coupled vibration model is established. Considering the factors such as the vehicle type, driving speed, vehicle weight and bridge frequency, the vehicle-bridge coupling vibration simulation is carried out for four standard prefabricated concrete hollow slab Bridges. The research shows that the impact coefficient increases with the increase of the vehicle speed and vehicle weight, whileit decreases with the increase of bridge frequency. Among various factors, the speed of the vehicle has the most influence on the impact coefficient. |
