| 摘 要： | 为了保持竞争力,欧洲的飞机工业要求降低开发和使用成本,短期和长期分别降低20%和50%。为了实现这一目标,欧盟在框架计划下支持了一系列复合材料加筋结构后屈曲技术相关的研究项目。飞机复合材料加筋板具有较强的后屈曲承载能力,在飞机设计中可大幅提高结构的承载效率。本文介绍了欧盟在该领域的发展概况,从项目背景、目标、开展的工作、分析方法以及研究成果等方面阐述了欧盟在第五、第六和第七框架及其他项目下支持的复合材料加筋结构后屈曲设计分析技术相关研究项目,并分析了该领域技术的发展趋势及带来的启示。

| Abstract: | composite stiffened panels have considerable post-bucking potential capacity load that can substantially increase loading efficiency in aircraft design. In this paper, review on the EU research of design and analysis of stiffened composite panels including post-buckling are recommended. The relevant literatures are reviewed from the aspects of background, objectives, work packages, achievements, and analysis methods of projects. Finally, the trend of future fiber composite panel is introduced and the enlightenment of what these researches bring to us is also summarized. |
