A Layout Optimization Method of Composite Wing Structures Based on Carrying Efficiency Criterion
2011
Chinese Journal of Aeronautics
A two-level layout optimization strategy is proposed in this paper for large-scale composite wing structures. Design requirements are adjusted at the system level according to structural deformation, while the layout is optimized at the subsystem level to satisfy the constraints from system level. The approaching degrees of various failure critical loads in wing panels are employed to gauge the structure's carrying efficiency. By optimizing the efficiency as an objective, the continuity of the
