摘要

典型柔性相似结构的耦合动力学建模与参数失调下系统的振动控制问题对航天结构设计具有重要意义。基于拉格朗日法和最小二乘法,完成了系统的耦合动力学建模和响应解耦处理,并进一步建立了柔性相似结构参数失调情况下的振动主动控制模型。最后完成了相关仿真分析,研究了结构参数失调情况下的系统模态局部化问题,振动控制仿真结果表明本文提出的基于响应解耦实现参数失调情况下系统的振动控制具有显著效果。

Abstract

Coupled dynamic modeling and vibration control of flexible similar structures with detuned parameters are important to 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. From 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.
