Vehicle Scanning of Bridge Frequencies
General Theory
This chapter focuses on the dynamic interaction, especially the frequency aspects of such an interaction, between the vertical vibrations of the moving vehicle and the bridge, with equal emphases placed on both of them. It adopts a modal superposition approach to derive the solutions for a vehicle bridge system, with the vehicle simulated as a sprung mass and the bridge as a simply supported beam. One implication is that if the dynamic response of a beam under moving loads can be accurately monitored, the recorded data, when processed in real time, can be used for detecting the moving speeds of vehicles over the beam, at least from a theoretical point of view. Compared with the numerical approaches, the approximate approach has the advantage that the key parameters involved in each phenomenon can be clearly identified and physically interpreted.
