摘要：
Coupled dynamic modeling and vibration control of flexible similar structures with detuned parameters are important for designing aerospace structures. The coupled dynamic model of a system was established with Lagrange method and its responses were decoupled based on the least square method. Furthermore, the active vibration control model was built and simulated to study the suppression of unstable responses of flexible similar structures with detuned parameters. Finally, the system modal localization caused by detuned parameters was simulated and analyzed. According to vibration control simulation results, it was indicated that the proposed active vibration control method for flexible similar structures with detuned parameters based on their decoupled responses is effective. © 2017, Editorial Office of Journal of Vibration and Shock.
