Technical research on deformation correction of composites stringer parts
According to the deformation correction of the composite stringer parts,the shape surface correction method of discrete distribution point and variable angle,the multi-region thickness offset algorithm based on the modified shape surface and the automatic segment bridging method of transition area are proposed respectively.The deformation correction system of composite material parts was developed based on CATIA/CAA,and then the digital modules of stringer parts were used as an example for verification,the time of manual correction and automatic correction were recorded respectively.The comparison results show that the proposed deformation correction method and the developed stringer deformation correction system can effectively improve the generation efficiency of the spring-back deformation correction process.
