飞机结构中柔性件装配偏差分析与控制研究进展

飞机柔性结构的装配偏差分析与控制一直是飞机装配中的难点,随着复合材料在飞机结构中的广泛应用,这一问题越发明显.采用预浸料固化工艺的复合材料零件具有制造偏差大、非主应力方向在装配过程中容易损伤等特点,对柔性件装配中的偏差分析和控制提出了更高的要求.如何合理地进行容差分配、工艺补偿、过约束装配以满足装配后的性能要求,是目前...

Research Progress on Analysis and Control of Assembly Deviation of Flexible Parts in Aircraft Structures

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.
