【Abstract】 Based on the theory of structural vibration control,this paper carries out spatial FEM(finite element method) analyses and vibration control researches on an actual model arch bridge.Discussions are made on the installation sites of TMD(tuned mass damper) and MTMD(multiple tuned mass damper),and intelligent designs for their parameters.The numerical re-sults show that a structure’s dynamic responses under the action of moving loads are effectively reduced with the proper installation sites and rational parameters of the vibration dampers.更多还原
