The invention discloses a method and system for aircraft metal structure reinforcement repair strength and stiffness compliance. The method includes determining basic structural type of an aircraft metal structure, and determining strength and stiffness conformity of aircraft metal structure according to the basic structure type of the aircraft metal structure. The system includes two modules: thebasic structure type determination module of aircraft metal structure and the basic structure type reinforcement and repair module of aircraft metal structure. The system also includes a memory and aprocessor. Through the invention, the aircraft user can directly carry out the reinforcement and repair of the reinforcement and repair structure on the basis of meeting the requirements of the reinforcement and repair strength and rigidity of the aircraft metal structure, thereby reducing the reinforcement and repair difficulty of the aircraft structure and shortening the repair cycle, and improving the utilization rate of the aircraft; In addition, the exchange of information between aircraft users and aircraft design units will not lead to understanding deviation and high reliability, which can be widely used in the field of metal structure reinforcement and repair technology.
Description
technical field [0001] The invention relates to the technical field of reinforcement and repair of metal structures, in particular to a method and system for reinforcement and repair of aircraft metal structures to meet the strength and stiffness requirements. Background technique [0002] Glossary: [0003] Structure: Refers to components whose main function is to bear and transmit loads. [0004] Rod: Refers to the aircraft structure whose basic deformation is axial tension and whose axial dimension (length) is much larger than the cross-sectional dimension. [0005] Sheet bending (formed section): Refers to the rod-type aircraft structure formed by sheet bending. The transverse thickness of the sheet bending parts is the same. [0006] Extruded section: refers to a rod-like aircraft structure that is extruded from a metal billet through a die. Extrusions generally vary in transverse thickness, with thicker flanging root regions. [0007] Sheet: Refers to an aircraft ...
