介绍了一种自适应柔性机翼后缘变形控制优化设计方法,该方法采用了由单个驱动器驱动的单块式分布柔性结构。该方法的关键在于设计一种合适的柔性后缘结构拓扑形式,使该自适应柔性机翼后缘能够达到精确的变形。阐明了柔性结构拓扑优化设计的数学模型,针对自适应柔性机翼后缘概念设计提出了基于参数化分析的拓扑优化设计方案,并进行了工程化圆整和尺寸优化。最终,通过非线性有限元分析和功能测试,验证了本文提出的柔性后缘优化设计方法的合理性。

Optimal design of adaptive compl iant trailing edge based on parametric analysis

The research introduces a kind of optimal design method of shape control for adaptive compliant trailing edge. The key design issue of the approach is the synthesis of a suitable topology for the compliant trailing edge which can produce a precise deformation.This paper illustrates the mathematic model of the topological optimization of compliant structures, and proposes a topology optimal design method based on parametric analysis for compliant trailing edge of adaptive wing.In this approach the engineering roundness and dimensional optimal procedure are followed.Finally,the optimal design method for compliant trailing edge is validated by a nonlinear finite element analysis and a functional test.
