Aerodynamic Characteristics of Vehicle-Bridge System under Cross Wind: Wind Tunnel Test System with Moving Vehicle Model

  • 摘要: 为考虑侧向风作用下车辆运动对车-桥系统气动特性的影响,针对车-桥系统气动绕流的特点,研制了一 套移动车辆模型风洞试验系统,在风洞中实现了侧向风作用下车辆运动过程中桥梁和车辆各自气动力的同步测 试.该系统可以较方便地改变来流风速、车辆运动速度、测试对象以及车辆与桥梁的相对位置等.根据测试信号 时程的特点,提出了相应的数据处理方法,分析了车辆运动过程中桥梁和车辆动态气动力的变化特征.试验结果 表明,桥梁和车辆的气动力信号较稳定,试验结果比较可靠.
