摘要
本文基于运载火箭贮箱筒段内撑工装撑出方式,通过有限元法,对筒段内撑变形进行数值模拟,研究筒段在内撑工装不同撑出量的作用下,其相应应力应变状态、径向变形,获得内撑工装撑出量与径向变形关系。
Based on the push-out mode of the carrier rocket section inner support fixture,the finite element method was used to numerically simulate the stress,strain and radial deformation by different deformation of the inner support displacement.and the relationship between the push-out quantity of the inner support fixture and the radial deformation of the cylinder section was obtained.
