Resonance reduction for linked train cars moving on multiple simply supported bridges

Popis výsledku v původním jazyce

The dynamic interaction of a moving train over a series of railway bridges with equal spans can result in a coupled vibration problem of wave transmission between two periodic structures. Dual resonance occurs when both systems vibrate in phase and the train travels at a resonant speed. The objectives of this paper are to (1) develop an active pitching resonator (APR) to attenuate resonance waves in a train, (2) study the dispersion relation for pitching motion control of periodically linked train cars, (3) investigate the key parameters that affect the dispersion band gaps of wave attenuation in a train, (4) present an active vibration cancellation method to enhance the control performance of the APR, and (5) demonstrate the effectiveness of using the optimal APRs to reduce resonance of a moving train. Through dispersion analysis, the optimum APR can not only shift the target frequency level away from resonance of a moving train, but also create a wide resonance band gap to reduce wave transmission in the train. Finally, the effectiveness of the optimum APR unit in reducing the resonance and attenuating the waves of a train travelling over multiple-span simple beams is demonstrated by dynamic finite element analysis of the train-bridge interaction.
