摘要：
In order to address severe slewing vibration in ultra-long flexible booms, the mechanism identification and active control of the slewing vibration were considered. Firstly, a simplified dynamical model of a slewing boom system was built according to the finite element method, and the slewing characteristics of the model were analyzed. Secondly, the active vibration control method was presented, which combines the algorithms of modal filtering and optimal pole assignment. Finally, the test platform based on NI instrumentation was implemented and the active vibration control experiment was carried out. The experimental results showed that the damping ratio of the controlled slewing system increases and the slewing vibration of the boom tip obviously decreases, which validates the effectiveness of the proposed method. © 2016, Editorial Office of Journal of Vibration and Shock.
