考虑结构动力学与颤振约束的颤振缩比模型优化设计

doi:CNKI:11-1929/V.20110126.1718.002

Abstract

Abstract: For the load-carrying structures of original model and scaled flutter are different, their aeroelastic characteristics may not be matched when their structural dynamics are matched. For this problem, a method is presented of designing a scaled flutter model which takes into consideration both structural dynamics and flutter constraints; a process of using the genetic/sensitivity-based hybrid algorithm to solve this problem is built and the method of choosing objective functions and constraint conditions is discussed. With an example of a scaled flutter model design, the validity of this method is verified. This example indicates that the design optimization method considering both structural dynamics and flutter constraints possesses better applicability than the design optimization method considering structural dynamics only.

Key words: aeroelasticity, scaled model, flutter, structural dynamics, design optimization
