礼花弹跌落起爆原因分析及防爆对策研究

Study on Detonation Mechanism of Shell Dropping and Countermeasures

通过分析礼花弹跌落时的受力情况,研究了礼花弹跌落起爆的原因。发现了礼花弹弹体是跌落试验中的起爆点,礼花弹的包装结构、烟火药机械感度、弹体规格等因素对礼花弹的跌落起爆都有影响;并提出通过优化设计礼花弹的包装结构来防止礼花弹的跌落爆炸。

Based on the study of the forces for shells in drop test, the explosion reasons of shell dropping was found. It is found that the package structure of shell, the composition mechanical sensitivity, as well as the size of shell have effects on shell dropping explosion. Meanwhile, through optimizing the package structure, the measures to prevent shell dropping explosion were proposed.
