Abstract
In order to reduce the frequency of major safety accidents in the bridge construction process, and to realize the real-time monitoring and accurate monitoring of the bridge construction process, a novel excitation device for vibration modal identification and structural vibration reduction is proposed in this paper. The excitation device mainly takes the rotating eccentric mass actuator as the core, uses the centrifugal force of the rotating mechanism to provide internal excitation to the structure, and has the advantages of easy control, low energy consumption, low cost and so on. The research results show that the exciting device has a wide application prospect in structural vibration modal identification and structural vibration reduction, and can effectively reduce the frequency of major safety accidents in the process of bridge construction.
