Development of Deformation Correction System for Edge Strip Composite Parts
Composite materials have high specific strength,specific stiffness and designability,which have been widely used in aircraft manufacturing.However,due to the influence of springback deformation and other factors,the geometric accuracy of parts is low,and the problem of composite material deformation correction urgently needs to be solved.Aiming at how to standardize and rapidly build the mathematical model of composite material deformation correction process,this paper put forward the automatic tracking,the discrete points and so on to assist the generation of contour surface,proposed the merge sort method,interpolation search algorithm and so on to assist the generation of inner surface.Some surface processing methods used in mathematical model construction were listed,and the deformation correction system of composite parts was developed under CATIA environment.The overall efficiency is improved by 734.5%after modification,which shows that the method can construct the technological mathematical model efficiently and normatively,and improve the generation efficiency of technological mathematical model.
