【Abstract】 This paper studies vibration response problem of a simple beam structure model under action of moving loads.The model can be used as the simplified model when there are trucks passing through the bridge.The relevant theory of active control is used to establish the velocity feedback control model and the displacement feedback control model.The results from the experiments indicate that the feedback control of the displacement and velocity observers can make the vibration of bridge model obtain effective inhibition and bridge model increase its safety.更多还原
