摘要
火药床在点、传火过程中存在严重动态压缩现象,压缩波有可能导致火药颗粒破碎、形成热点甚至引起爆炸.该文以活塞驱动HMX炸药颗粒床所产生的动态压缩为例,对压缩波初态、终态及结构进行了分析,得到一些有价值的结论,并与实验结果进行了比较,两者吻合很好.
Experimental results showed that dynamic compaction occured during the ignition andflame spreading processes of propellant beds.It is generally accepted that the compaction wavemay lead to the propellant particles break up,formation of hot spot and even detonation.In thispaper,the piston driven compaction problem for HMX explosive bed was investigated as anexample to determine the initial state,end state and structure of the compaction wave.Somevaluable conclusion was obtained.There are good agreement between the predicted results andexperimental results.
