摘　　要：研究了军用飞机在服役环境下的湿热谱和复合材料结构的湿扩散以及 相应的湿应力场，给出了某军用飞机模型复合材料机翼结构的分析数值结 果。所给出的分析方法和数值分析结论对军用飞机结构设计和分析工作者有 参考价值。The paper investigates the following two aspects:(1) study of hydrothermal spectrum of the service environment of the military airplane by using 'reasonable weighted average method' ; (2) analysis of moisture diffusion and induced stress field of the composite structure for the military airplane by using finite element method. Numerical results are presented for a composite wing's structure of the military airplane model. The numerical method and conclusions given may be helpful for the designers and analysis of the military airplane structure.
