Vibration Suppression of Vehicle-Bridge-Interaction System using Multiple Tuned Mass Dampers

In this study, vibration suppression of vehicle-bridge interaction system has been studied in terms of bridge dynamics. In vibration suppression, some configurations of tuned passive mass dampers have been considered. Motion equations of vehicle and absorbers are coupled with the motion equation of the bridge beam using first four mode of beam and Lagrange equations. Then the coupled equation of vehicle-bridgeabsorbers (VBA) has been solved using the fourth order Raunge-Kutta algorithm. It is proved that the configuration of the absorbers that are placed on the anti-nodes of first and second mode shapes of the bridge beam is the most effective one of all others.
