摘要

摘要: 本文对不同初温、不同粒度的火药床进行了准静态压缩实验，测定了火药床压缩过程的应力-应变关系，得到了随初温变化的颗粒间应力公式。把经过压缩实验后的火药在密闭爆发器重进行了燃烧实验，并同未压火药进行了比较，发现火药表面致密和火药破损是影响火药燃烧特性的主要因素。

Abstract: In this paper, quasi-static compaction experiments of propellant beds with different initial temperatures and particle sizes were performed. Stress-strain relations of the propellant beds during the compaction were measured. The relationship between the intragranular stress and the initial temperature were obtained. Combustion experiments in the closed bomb were conducted by using the standard propellant and the propellant after being compacted. The results show that the surface densification and damage of the propellant are the main factors that influence the combustion characteristics of the propellants.
