摘　　要：双曲形复合材料构件固化变形是影响零件质量和几何精度的关键问题之一,为了提高双曲形复合材料构件成型几何精度,本文提出了一种基于试验数据的变形修正方法,详细阐述了试验数据获取、去噪和数据对齐以及基于多截面的试验数据搜索法和镜像法等关键问题;并基于CATIA/CAA二次开发技术开发了修正模块,该模块能够对双曲形复合材料构件的固化变形进行有效补偿。以某机上双曲形零件为例进行试验验证,经过该模块修正后,零件的制造误差显著减小,证明了该方法的有效性和可行性。本研究结果对于提高双曲形复合材料构件的制造精度和性能具有重要意义。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.
