摘要
为研究不同风向角下高速动车组的动力学性能,利用多体车辆动力学研究方法,对不同风向角下的某型动车组的车辆运行安全性进行仿真模拟分析。把气动载荷处理为时间函数,将其输入多体动力学软件,对动车组在风载作用下的动力学性能进行仿真分析。利用8节连挂动车组模型,分别分析各辆车在不同风向角下的运行安全性。分析发现:头车受风载的影响最为明显,在风速20 m/s、车速300 km/h下的工况相较于在风速25 m/s、车速200 km/h下的工况对列车运行安全性影响大。其中在风速20 m/s、车速300 km/h下的工况105°风向角的风载对列车运行安全性影响最大。
In order to study the dynamic performance of high-speed Electric Multiple Units under different wind angles,the vehicle running safety of a certain type of Electric Multiple Units under different wind angles was simulated and analyzed by using the multi-body vehicle dynamics research method.The aerodynamic load was treated as a time function and input into the multi-body dynamics software to simulate the dynamic performance of Electric Multiple Units under wind load.The operation safety of each vehicle under different wind angles was analyzed by using the eight-car Electric Multiple Units models.The analysis shows that the head car is most affected by the wind load.The speed of 300km/h with wind speed of 20m/s has a greater impact on the safety of train operation than the speed of 200km/h with wind speed of 25m/s.The wind load at 105°wind direction angle has the greatest influence on train operation safety when the train speed is 300km/h with the wind speed of 20 m/s.
