摘要

为了抑制随机失谐星载天线结构的振动局部化及其导致的振动控制失效问题，本文建立了径向肋天线结构的单肋多自由度集中参数模型，提出了一种衡量结构整体振动模态品质的局部化因子；分析了失谐肋的安装顺序对结构整体模态振型的影响，利用遗传算法对失谐肋的安装顺序进行了减振优化，并评估了失谐优化对天线振动控制系统性能的提升。结果表明：对于一组具有特定随机失谐参数的径向肋，基于本文的模态局部化因子和智能搜索算法可以快速、准确地得到其最优或近似最优安装顺序，不仅能大大改善天线整体振动模态品质、降低结构振动响应，还能提高天线结构控制系统效能。

Abstract

To suppress the vibration localization and improve the vibration control system of mistuned space-borne antenna structure, a single rib multi-freedom lumped parameter model of radial rib antenna was established in this paper. Firstly, a mode localization factor for measuring the overall quality of structural vibration mode was proposed. Secondly, the influence of the certain mistuned ribs arrangements of the antenna on the overall structural vibration mode was studied. Finally, the problem of optimal design of the mistuned ribs arrangement was investigated by the genetic algorithm (GA), and the effect of optimization of the mistuned ribs arrangement on enhancing the performance of vibration control system was assessed. The results show that: for a group of certain random mistuned ribs, the optimal or approximate optimal mistuned ribs arrangement can be quickly and accurately obtained by the genetic algorithm and mode localization factor proposed in this paper, and the optimal mistuned ribs arrangement can not only greatly improve overall quality of structural vibration mode, reducing the structural vibration response, but also improve the efficiency of the vibration control system of the antenna.
