摘要: 复合材料结构相似风洞颤振模型是一种先进的颤振模型结构形式,对于新一代飞机研制所必经的风洞颤振试验有重要意义。对于先进的风洞颤振模型,其模型外形几何参数以及整体刚度、刚度分布、整体质量、质量分布等特征参数均有较高的精确性要求,加之复合材料性能组成复杂,加工性能较差,传统制造方法不能实现对于该类产品的性能参数的精确保证,因此需要新的制造方法。针对复合材料结构相似风洞颤振模型的制造难题,利用复合材料的力学性能可设计性,实现对于颤振模型性能参数的精确保证,并提出了一种针对模型性能参数的精确制造方法。以此方法制造了一系列机翼,尾翼颤振模型。工程实践证明,该方法可以有效保证颤振模型的几何与性能特征参数的精确性。

Abstract: Being the subject of wind-tunnel testing, flutter model is an important part of modern aircraft designing. Widely acknowledged as one kind of advancing flutter model, composites structural-similar flutter model(ComSFM ) provides similar structural design to the original aircraft structure design. ComSFM are designed to be produced with high-precision of flutter feature. Functional parameters with high-precision could not be provided by applying the manufacturing method of traditional types of flutter model, while the manufacturing method of enhancing the strength or stiffness of composites structure could not be used in this situation, so the need of new type of manufacturing method of ComSFM is urgent. In this article, a brief introduction of flutter model designing and manufacturing is made. In purpose of solving the manufacturing problem of ComSFM, a precise manufacturing method of functional feature with high-precision is provided. And by using this method, several types of flutter model are manufactured. The manufacturing method is proved to be valid in flutter model manufacturing practices.
