Dynamic Analysis of Railway Bridge Under High-Speed Trains

This article reports on a study of the dynamic interaction between high-speed train and bridge; the study includes both theoretical analysis and field experiment. The authors establish a computational model of train-bridge system. Each vehicle is described by 27 degrees of freedom. The bridge is modeled by modal superposition technique. The measured track irregularities are taken as the system excitation. The authors use as a case study the historical data of the China-Star high-speed train running through a bridge with 24 m-span PC box girders on the Qin-Shen Special Passenger Railway in China. The dynamic responses of the bridge are calculated. These included dynamic deflections, lateral amplitudes, lateral and vertical accelerations, lateral pier amplitudes, and the vehicle responses such as derail factors, offload factors, wheel/rail forces and car-body accelerations. The authors then verify the proposed analysis model and the solution method through the comparison between the calculated results and the real world measured data.
