数值模拟技术在飞机复合材料结构制造中的应用

复合材料结构件在航空领域得到广泛应用，但制造中产生严重的翘曲变形影响外形精度和装配连接。因此，对其制造工艺的研究日益重要，尤其是对带有复杂轮廓型面复合材料整体结构件的制造工艺。本文对复合材料结构成型工艺中固化变形机理进行了分析，阐述了变形控制模拟技术的发展和其在飞机结构制造中应用的必要性，并以实例证明数值模拟技术是进行...

Application of Numerical Simulation Technology on Composites in the Aircraft Manufacture

The composite materials and structures are used popularly in the area of the aviation, but the warp of the composite structures during the manufacture process affects the precision of structure outline and assembly. So the study for manufacturing process becomes more and more important, especially for the manufacturing process of the overall composite structure with complex contours. In this paper the curing deformation mecha- nism of the composite structure is analyzed, the development of the numerical simulation technology of compos- ites deformation control and its necessity in the aircraft manufacture are described. Examples are used to show that this technology is an effective method to forecast and control the deformation.
