摘要

分离结构是航天运载器上十分关键的部位，膨胀管分离装置作为一种清洁的分离结构，被广泛应用于火箭、卫星等的分离部位。本文使用LS-DYNA中的流固耦合算法对扁平管组件（扁平管、填充物、炸药索）进行了有限元仿真分析，并进行了实验验证，仿真与实验结果吻合得较好。在此基础上，分别改变扁平管的壁厚，填充物的密度、弹性模量，通过有限元仿真分析了扁平管上两个特征点的膨胀速度、膨胀位移及扁平管动能的变化规律，获得各参数对于扁平管膨胀变形的影响，对于设计扁平管组件具有很大的指导意义。

Abstract

Separation structure is a key part of a space launch vehicle.The expanding tube separation device is widely used at the separating position of space launch vehicle.as a clean separation structure.Here,the finite element simulation analyses were performed for a flat tube assembly including flat tube,filler and explosive rope using the fluid-solid coupled algorithm in the software LS-DYNA and test verifications were conducted.The simulation results agreed well with those of tests.Furthermore,changing wall thickness of the flat tube,mass density and elastic modulus of filler,respectively,the variation laws of expanding velocity and expanding displacement of two feature points on the flat tube and the tube’s kinetic energy were analyzed through the finite element simulation to obtain the effects of these parameters on the flat tube’s deformation.The results provided a guide for the design of flat tube assemblies.
