Abstract：This paper optimizes the structureof composite material thrust skirt.The stress ofanewcomposite material thrust skirtunderload isanalyzedbyusingANSYSfinite element software，and then thecompositematerialthrustskirt structure isoptimizedforthreetimes.Thestaticanalysisofthecompositematerialthrustskirtafterstructuraloptimizationis carried outbyusing finiteelement software.Itisfoundthat thedeformationand stresstateofthecomposite materialthrust skirt is improvedafter structuraloptimization，whichcan providesomereferenceforthesubsequentdesignofcomposite material thrust skirt.

Keywords：composite material thrust skirt；structural optimization；finite element method

1引言
