摘要

膨胀管分离装置是航天运载器上一种常用的线式分离装置，其能量源为扁平管组件（炸药索、填充物和扁平管）。为研究扁平管组件的能量输出效率，首先，通过实验的方法，将扁平管组件插入1060纯铝筒中，测量铝筒外壁特征点的速度和位移变化历程，并将实验后的实验件进行线切割，测量其内径的变化。对上述实验过程进行有限元仿真分析，仿真结果与实验结果对应得较好。进而通过仿真分析结果获得铝筒的塑性变形能，作为扁平管组件输出的有效能量，其占炸药总能量的比值为能量输出效率，得到扁平管组件的能量输出效率约为22.8%。最后，在有限元分析中改变填充物的材料参数，发现在一定参数范围内，扁平管组件的能量输出效率随填充物的密度、弹性模量和泊松比的增加而增加。

Abstract

The expanding tube separation device is a commonly used linear separation device on space launch vehicle, whose energy source is a flat tube assembly including explosive cord, filler and a flat tube.Here, to study the energy output efficiency of the flat tube assembly, firstly it was inserted into a 1060 pure aluminum cylinder with the experiment method.Then velocity and displacement time histories of characteristic points on outer wall of the aluminum cylinder were measured.Wire cutting was done for specimens after experiment to measure their inner diameter’s variation.The above experimental process was simulated with the finite element method.The simulation results agreed well with experimental ones.The plastic strain energy of the aluminum tube was obtained by the finite element simulation, and taken as the effective energy output by the flat tube assembly, and its ratio to the total energy of explosive was the energy output efficiency of the flat tube assembly.Results showed that the energy output efficiency of the flat tube assembly is about 22.8%; within a certain filler’s material parameter range, the energy output efficiency of flat tube assembly increases with increase in filler’s density, modulus and Poisson’s ratio.
