摘　　要：针对全备弹状态下开展破片撞击试验时存在安全风险较大、引信响应情况难以准确判断及不同弹体厚度对引信响应特性影响不明等问题,开展破片撞击环境下引信响应特性研究,揭示了破片撞击下引信传爆序列装药响应机理,分析了破片撞击不同厚度模拟弹体条件下引信响应后的输出特性,得到了模拟弹体厚度对引信反应等级的影响规律。结果表明:破片撞击引信时传爆药发生反应主要由冲击波造成,并在冲击波反射增强后发生剧烈反应;随着模拟弹体厚度增大,引信的输出压力逐渐减小,反应等级逐渐降低,二者具有明显的相关性;试验测得了不同厚度模拟弹体引信在破片撞击下的输出压力和反应等级,验证了破片撞击不同厚度模拟弹体条件下引信响应规律的准确性。该研究可为破片撞击全备弹引信的响应特性分析提供一定参考。The fuze response characteristics under the fragment impact environment were studied,and the response mechanism of fuze detonation sequence charge under the fragment impact was revealed.The output characteristics of fuze response under the condition of fragment impact on simulated projectile with different thickness were analyzed,and the influence law of simulated projectile thickness on fuze response grade was obtained.The results showed that the reaction of the booster explosive was mainly caused by the shock wave when the fragment impacts the fuze,and the violent reaction occured after the shock wave reflection enhanced.As the thickness of the simulated projectile increased,the output pressure of the fuze gradually decreased,and the reaction level gradually decreased.The output pressure and reaction level of the simulated projectile fuze with different thickness under the impact of fragments were measured,and the accuracy of the fuze response law under the condition of fragment impact on the simulated projectile with different thickness was verified.This study could provide references for the response characteristics analysis of the fragment impact on the full stand-by projectile fuze.
