安全型强光爆震弹的设计与试验

Design and Test of Safety Strong Acousto-Optic Bomb

为了提高强光爆震弹的安全性,防止破片对有生目标造成过度伤害,对新型强光爆震弹采用无破片弹体结构设计,选用开孔外壳和内壳相结合的双层腔体结构。利用仿真软件分析了内壳材料厚度、喷口的数量和直径等对声压效应的影响,对结构参数进行了优化。在此基础上,加工样弹并开展了结构可靠性试验和声光威力试验。试验结果表明:弹药爆炸时外壳体不发生破裂,破片被滞留在弹体内部,不会产生杀伤性破片,并具有较好的复杂环境适应性;强光爆震弹的平均闪光强度为1.57×10^7 cd,平均声强为151.7 dB,满足技术要求。

In order to improve the safety of strong acousto-optic bomb and avoid excessive damage to persons from fragments,a new type of strong acousto-optic bomb was designed based on fragmentless projectile.A double-layer cavity structure with an open shell and an inner shell has been adopted and designed.The simulation software was used to analyze the effects of inner shell thickness,nozzle number and diameter on the sound pressure,then the design scheme has been optimized.Based on these analysis,the sample bombs have been processed,and structural reliability test and acousto-optic power test have been carried out.They turn out that the outer shell of bombs don’t break when explodes,and the fragments are detained inside the ammunition body,which will not produce lethal fragments.It has good adaptability to complex environment.The average flash intensity of bombs is 1.567×10^7 cd,and the average sound intensity is 151.72 dB,which satisfies the technical requirements.
