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(fù)合材料推力裙是固體火箭發(fā)動(dòng)機(jī)殼體的關(guān)鍵部件，用于實(shí)現(xiàn)殼體級(jí)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）
