某小型强光爆震弹爆炸仿真研究

Explosive Simulation on a Miniaturization Stun Grenade

为开展某小型强光爆震弹的使用安全性分析,基于LS-DYNA仿真平台建立了某小型强光爆震弹爆炸体的爆炸仿真模型,分析了破片分布规律和速度变化情况,评估了该弹的杀伤半径。结果表明,该弹破片大小分布不均,爆炸体中部产生的大质量低速破片是主要杀伤源,杀伤半径约为2.33 m。该研究可为小型强光爆震弹及同类弹药的研制和应用提供依据。

To verify the operational safety of the designed miniaturization stun grenade,the explosive simulation model was established based on LS-DYNA.The distribution rule of fragments and the change of velocity were analyzed,and the safety radius was evaluated.The results show that the fragment size distribution is uneven.The large mass and low velocity fragments produced in the middle of the explosive body are the main killing source,and the safety radius is about 2.33 m.This study provides a scientific basis for the development and application of the miniaturization stun grenade and similar munitions.
