结构动力学与颤振约束下无人机机翼优化设计

提出了同时考虑结构动力学约束和颤振约束的优化设计方法，建立了利用规划优化算法求解问题的流程，并将其融入大型CAE软件系统HAJIF2013中，研究了优化问题中目标函数和约束条件的选取方式。以某型无人机机翼颤振模型为算例，利用拉盖尔迭代方法自动计算颤振速度，并对优化算法的有效性进行了验证。研究表明，所提出的优化设计方法有效，实现了整个优化求解流程的自动化，对工程设计具有指导意义。

Design Optimization of Unmanned Aerial Vehicle Model under Structural Dynamics and Flutter Constrains

In this paper , a method is presented which takes into consideration both structural dynamics and flutter constraints ,a process of using the mathematical programming method to solve this problem is built and the method of choosing objective functions and constraint and bring into a large number of CAE software HAJIF2013,With an example of a unmanned aerial vehicle wing ,the Laguerre iterative method has been presented into this system and the validity of this method is verified .This example indicates that the design optimization method considering both structural dynamics and flutter constraints possess is ef -fective ,automatically and useful in engineering design .
