VIBRATION REDUCTION FOR THE TRAIN-BRIDGE SYSTEM WITH OVERHANGING BEAM EFFECTS

本文關鍵字:HIGH SPEED RAILOVERHANGING BEAMRESONANCEVIBRATION REDUCTIONVBI DYNAMICS

本文摘要As a train passes through a rail bridge with overhanging beams at high speeds, the overhanging beam would be subjected to intensive vibrations and then excite the running trains over it, which may build up the dynamic response of the train-bridge system. In this study, a finite element modeling that can account for the dynamic interaction of train-bridge coupling system will be used to simulate the dynamic response of the coupling system. To reduce the amplification effect of overhanging beams on the train-bridge system, a set of rotational restraint devices will be installed on the adjacent overhanging beams. From the numerical results, the proposed approach can effectively reduce the amplification of overhanging beams on the train-bridge system.
