STRUCTION OPTIMIZATION OF COMPOSITE CASE DOME WITH HOLES BASED ON CDOE

Abstract

Abstract: Numerical was used to analyze the foe dome with holes of filament winding composite case. Based on the CDOE, 8 cordorinte value of the fore dome were defined as design point by establishing surrogate model and GDO. Meanwhile, target function was introduced which contained weight of the foe dome with holes and Mises-strain along the fiber located in the pitch circle of the hole edge for optimization design.The results reveal that the structure of the foe dome was correspond,and strain distribution located in the pitch circle was reasonable,the weight of structure was decreasd by 1.85%.

Key words: filament winding composite, fore domes, optimization design
