Abstract

With the continuous improvement of the bridge span, the phenomenon of vortex-induced vibration (VIV) in railway bridges can disrupt the normal functioning of railway systems. This paper establishes a method for wind-train-bridge-VIV, focusing on the dynamic responses of the bridge and the impact of the train during such events. Additionally, the study evaluates the effects of critical parameters like the amplitude of VIV, the train's operational velocity, and the initial phase angle of VIV on the dynamic reactions of the train and the bridge. The allowable values of VIV for the railway bridge are also investigated. The findings reveal that the three key factors substantially impact the dynamic reactions experienced by the railway bridge and the train. Notably, the VIV amplitude is a dominant factor in the vertical dynamic response, exerting a substantial impact on train ride comfort. Consequently, it is imperative to impose limitations on the VIV amplitude in railway bridges to maintain operational efficiency and passenger comfort.

涡激振动对风-车-桥耦合系统列车动力学及安全舒适性的影响

随着桥梁跨径的不断增大，铁路桥梁的涡激振动现象会影响铁路系统的正常运行。本文建立了一种风车-桥梁-涡激振动的方法，重点研究了风车-桥梁在这种情况下的动力响应和列车的冲击。此外，研究还评估了涡激振动幅值、列车运行速度、涡激振动初始相位角等关键参数对列车与桥梁动力反力的影响。并对铁路桥梁的涡激振动允许值进行了研究。研究结果表明，这三个关键因素对铁路桥梁和列车所经历的动力反应有实质性影响。值得注意的是，在纵向动力响应中，动幅是一个主导因素，对列车的乘坐舒适性有很大的影响。因此，为保证铁路桥梁的运行效率和乘客舒适度，必须对桥梁的动振振幅加以限制。

期刊介绍： The objective of the journal is to provide a means for the publication and interchange of information, on an international basis, on all those aspects of wind engineering that are included in the activities of the International Association for Wind Engineering http://www.iawe.org/. These are: social and economic impact of wind effects; wind characteristics and structure, local wind environments, wind loads and structural response, diffusion, pollutant dispersion and matter transport, wind effects on building heat loss and ventilation, wind effects on transport systems, aerodynamic aspects of wind energy generation, and codification of wind effects. Papers on these subjects describing full-scale measurements, wind-tunnel simulation studies, computational or theoretical methods are published, as well as papers dealing with the development of techniques and apparatus for wind engineering experiments.
