Abstract Assembly deviation analysis and control of aircraft complaint structure is always a difficulty in aircraft assembly. With the extensive application of composite materials in aircraft structure, this problem is exposed more and more obviously. As the composite parts manufactured by prepreg curing process have the characteristics of large manufacturing deviation and easy damage in non-principal stress direction in the assembly process, so higher requirements are put forward for the deviation analysis and control in the assembly of flexible parts. It is a difficult problem for assembly of composite complaint parts at present, that how to carry out tolerance allocating, technological compensation and over-constrained assembly reasonably to meet the performance requirements after assembly. This paper expounded and summarized the research progress of the deviation analysis and control of flexible parts assembly in aircraft structure, and provided a reference for assembly of aircraft flexible parts.
