用ANSYS软件对固体发动机壳体后封头进行了外压屈曲分析.结果表明,在可承受相同内压条件下金属壳体后封头比复合材料壳体后封头有更高的承受外压能力;壳体后接头、喷管固定体对后封头承外压能力有加强作用;壳体后开口直径越大,临界屈曲载荷越大.

Buckling analysis on rear dome of solid rocket motor case was studied by means of ANSYS.Results show that the rear dome of metal case can support higher pressure than that of composite case under the same internal pressure.The case rear joint and the fixed body of the nozzle can reinforce the case rear dome obviously.Furthermore,the larger diameter of case rear aperture is,the greater critical buckling load of case rear dome is.
