强迫定位装夹对航空复合材料构件几何-物理装配性能的影响与协同保障
Effects of Forced Positioning & Clamping on Geometric and Physical Assembly Performances for Composite Structures and Collaborative Guarantee Strategies
摘要
Abstract
The large-size & thin-walled aviation composite structures had low forming accuracy and huge in-plane warping deformation.The accumulation of assembly errors,unexpected geometric gaps and shape deviations were prone to occur at the joining areas.In engineering,passive reduction actions,such as applying local clamping forces was usually applied,but uneven internal stress distri-bution and even internal damages would be occurred,which affected the mechanical performances of the structures in service directly.Firstly,the principle of forced positioning clamping was explained,and the affection on geometric accuracy and mechanical properties of weak rigid composite parts was analyzed.Secondly,starting from the analysis of two main aspects,i.e.optimization on forced clam-ping process parameters before assembly,and flexible positioning force&position adjustment of fix-tures during assembly,five key technologies were solved with detailed technical solutions,i.e.setting forced assembly force limits,reduction of geometric gaps,prediction of stress/damage evolution,re-verse optimization of forced clamping process parameters,and precise measurement of assembly stress&damage.Then the active control of shape&force coupling and macro & micro collaborative guarantee in the clamping processes for assembly performance,could be achieved.Finally,for the composite assembly structures,from the perspective of practical engineering applications,the future working focus towards high assembly quality and efficient,and low-cost assembly goals were pro-posed.关键词
