飞行器壁板结构热屈曲分析与试验研究进展

Review of the investigation on thermal buckling analysis and experiment for aircraft panel structures

高速飞行器在服役期间面临着严酷的高温环境,引起飞行器壁板结构屈曲失稳,从而严重影响飞行器结构的完整性和可靠性。本文从解析法、有限元法和试验综述壁板结构热屈曲行为的国内外研究进展,总结分析了各方法之间的优势与不足,为设计提高飞行器壁板结构抗热屈曲性能提供技术支撑。

Aircraft panel structures will be exposed to an extremely thermal environment during the servicelife, which will induce the buckling behavior of the local structures and present a great challenge for theintegrity and durability of aircraft panel structures. The thermal buckling behavior of aircraft panelstructures has been reviewed in the following three aspects： theory analysis, finite element analysis andexperimental analysis. The merits and defects of the above three methods have been compared, which willmake a significant technical support on the structural design for improving the anti-buckling behavior ofaircraft panel structures.
