Abstract

Abstract: Curing deformation of hyperbolic composite components was one of the key issues affecting part quality and geometric accuracy. The deformation correction method based on experimental data was proposed by this paper in order to improve the geometric accuracy of hyperbolic composite components and key issues such as experimental data acquisition, denoising and data alignment, as well as the multi-section experimental data search method and mirror method were elaborated on. A correction module was developed based on CATIA/CAA secondary development technology, which can effectively compensate for the curing deformation of hyperbolic composite components. Experimental verification was conducted using a hyperbolic part on an aircraft, and after correction by the module, the manufacturing error of the part was significantly reduced, demonstrating the effectiveness and feasibility of the method. The results of this study are of great significance for improving the manufacturing accuracy and performance of hyperbolic composite components.
