摘要

飞机翼面结构形状的控制设计是提高飞机性能的关键技术。本文以压电纤维复合薄膜（Microfiber Composite，MFC）为驱动器，研究了协同优化设计MFC驱动器结构参数与控制电压以使飞机翼面结构具有理想形状的方法。以MFC的电极宽度、电极指间距、MFC厚度、压电陶瓷体积分数等驱动器结构参数以及控制电压为设计变量，以控制偏差最小为优化目标，以驱动器的击穿电压为约束，建立了驱动器结构参数与控制电压协同优化设计的模型；通过分析MFC驱动器结构参数对驱动性能的影响，给出了最优的驱动器结构参数；针对类似机翼翼面形状的平板扭转型面，给出了驱动器结构参数与控制电压协同的最优控制设计。设计结果表明：对于扭转变形，多个不同控制电压控制的型面均方差是相同控制电压控制均方差的45%，分析结果验证了本文所建立的协同优化设计方法的有效性。

Abstract

The control and design of flexible support structure and warping surface for an aircraft is a key to improve its flight performance. In this paper

an integrated optimal design method for structural parameters and control voltages was presented by using Microfiber Composite (MFC) as a actuator to obtain the desired shape of the surfaces. An integrated optimization model of actuator structural parameters and control voltages was established for minimizing the control deviation through designing electrode width and separation

MFC thickness

the volume fraction of piezoelectric ceramic fiber and controlling the breakdown voltage of MFC. The optimal parameters of the actuator were given by analyzing and comparing the effect of structural parameters on the performance of surface. The warping of a wing surface was used as an example to validate the effectiveness of the method. The results show that the mean square deviation of the multi-voltage control is 45% that of the single voltage control. These results prove that the method presented has potential applications in design of aircraft wing warping.
