The invention belongs to the technical field of aircraft assembly coordination technology and composite material deformation and rebound deformation, and relates to a reversible deformation assembly method for weak-rigidity composite material parts. Before formal assembly of the product is not completed, pre-reverse deformation is applied to the product which is predicted to have deformation, assembly is completed in the state, and after stress release deformation of the assembled part is completed, the appearance of the part can return to the theoretical tolerance range of the appearance of the part. Practical verification shows that the weak-rigidity composite material part obtained after the technology is adopted is high in deformation correction speed and good in coordination accuracy, the assembling efficiency and the assembling quality of the weak-rigidity composite material structural part are greatly improved, the technology can be rapidly applied and popularized to assembling of similar composite material structural parts, and great economic benefits and social values are achieved.
本发明属于飞机装配协调技术、复材变形及回弹变形技术领域,涉及一种弱刚性复合材料零件反变形装配方法。在产品未完成正式装配前,对预计存在变形的产品施加预先的反变形量,在此状态下完成装配,完成装配后的部件在完成应力释放变形后,使部件的外形能回复到部件外形的理论公差范围内。经过实际验证,采用该技术后的弱刚性复合材料部件变形纠正速度快,协调准确性好,极大地提高了弱刚性复合材料结构件的装配效率和装配质量,且能快速推广应用到相似复合材料结构件的装配中,具有极大的经济效益及社会价值。
