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)
