| Abstract: | The optimization design of composite lay-up is of important significance for increasing the bearing capability of aircraft structure.Free-size optimization technology is the effective method to optimize composite structure.Based on the research of composite wing-box stiffness constraint,the wing panel lay-up is analyzed by the method of free-size optimization in this paper.The results show that in the given deformation constraint of wing tip the composites ply ratio and thickness of wing-box can be designed quickly and accurately,the optimized main force transmission path can be found,and the minimum weight is achieved by the free-size optimization. |
