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
復合材料推力裙是固體火箭發(fā)動機殼體的關鍵部件，用于實現(xiàn)殼體級間段連接或與其他部件的連接，是殼體的整體延伸[1]。（剩余4312字）
