| 摘 要： | 以芜湖长江大桥及高速列车为例，对车-桥系统进行了节段模型风洞试验研究。通过试验确定了桥上有车时，桥本身的气动力参数，以及列车在桥上时，列车本身的气动力参数，用计算机模拟了列车与桥梁所受的风荷载。所得的风荷载加到车-桥系统动力学方程中，可以计算风荷载对车-桥系统的动力作用

| Abstract: | The aerodynamic parameters of Wuhu Bridge over the Yangtze River and a high speed running on it were measured respectively by wind tunnel tests. The natural wind loads acting on the train and the bridge were simulated. The calculated wind loads are added into the dynamic equations of train and bridge to calculate dynamic effects of wind loads on train and bridge. |
