| 摘要: |
| 为解决民机复合材料结构实际修理过程中判断要不要修、能不能修的修理容限问题，根据已有成果和不足，提出了2种复合材料结构修理容限的完整求解方案和流程（基于波音公司修理验收要求的修理容限，满足设计许用应变值的修理容限），重点解决如何在同时考虑维修经济性和结构安全性情况下合理确定复合材料结构的修理上限；然后以受压复材加筋壁板为例，考虑穿孔损伤形式，结合有限元分析，分别应用2种求解方案计算了加筋壁板的修理容限。结果表明：2种修理容限求解方案得到的同一复材加筋壁板修理容限结果比较接近且合理，证明了2种修理容限确定方法的可行性，为民机复材结构损伤的工程化评估提供参考。 |

| Abstract: |
| In order to solve the problem of repair tolerance in the actual repair process of civil aircraft composite structure, by which it is judged whether to repair or not. Based on the existing results and shortcomings, this paper proposes two complete solutions and procedures for the repair tolerance of composite structure, focusing on how to determine the upper limit of repair under the consideration of both economy and safety. Then taking the composite stiffened wall panel under compression as an example, considering the damage of perforation, combined with finite element analysis, these two methods are used to try to calculate the repair tolerance of the stiffened panel respectively. The results show that the repair tolerance results of the same composite stiffened wall panel obtained by the two schemes are relatively close and reasonable, which proves the feasibility of these two methods, and provides a reference for the engineering damage assessment of civil aircraft composite structure. |
