Dynamic Response of Poles Built on Railway Bridges Under High-Speed Train Passages
In Japanese high-speed railways, large-amplitude vibration of railway poles built on bridge and catenary corruption related to the pole vibration have been reported. However, the dynamic behavior of poles built on bridges under high-speed train passages is poorly understood. This study focuses on the coupled dynamic behavior of poles and bridges. A numerical model considering such coupling was established by applying the finite element method, and its calculation accuracy was verified by comparison with the field measurement results. Then, the proposed numerical model is used to conduct a parametric study on the span length, pole position, and pole type. The result reveal that the rail-direction vibration of the pole built at the edge of the bridge was greater than of poles in other positions. Furthermore, the pole vibration is shown to increase sharply by the overlap of multiple resonances including the pole and bridge frequencies as well as the excitation frequency of the train in transit.
