摘要
为了解决轻型结构、复材结构和旋翼结构的颤振激励难题,文章首先对颤振激励技术的发展现状进行了简要介绍,进而对基于压电作动器的颤振激励技术的研究背景、工作原理、研究内容和发展趋势进行了详细分析和论证。通过一系列理论分析和地面试验研究表明,基于压电作动器的颤振激励技术成功对小型结构机翼进行了有效激励。该技术不仅扩充了国内颤振试飞的激励手段,而且可推广应用于轻型结构、复材结构和旋翼结构颤振试飞的结构激励。
In order to solve the problem of flutter excitation to the light-structure,the composite structure and the rolling wing,the paper introduce the actuality of flutter excitation in brief at first,then analyse and demonstrate the background,the working principle,the content of investigate and development direction to structure excitation based on MFC in detail.It was proved that the techn ology had excitated the LSW successfully through theory calculation and ground test.Not only can it expand the ways of flutter excitation in inland,but also can extend to excitate the light-structure,the composite structure and the rolling wing.
