摘要
针对引信受破片撞击时的安全性问题,提出了一种引信防护结构,通过在引信传爆管壳和引信壳体之间增加一层防护陶瓷,使得引信在受到破片撞击时能够通过陶瓷吸收部分动能,从而提升引信的安全性能。通过仿真与试验对比的方法,分析了无防护、氧化铝陶瓷和碳化硅陶瓷防护结构的抗破片撞击性能。结果表明:增加碳化硅陶瓷防护结构可使引信在破片撞击下的传爆药峰值压力降低82.6%,见证板凹痕直径降低4.8%,优于氧化铝陶瓷防护时的81.8%和2.58%。陶瓷防护能够有效提升引信抗破片冲击能力,碳化硅陶瓷的抗冲击效果优于氧化铝陶瓷。
In response to safety concerns related to the impact of fragments on fuzes,a fuze protection structure has been proposed.This structure involves adding a layer of protective ceramics between the fuze transmission tube casing and the fuze body to enable the fuze to absorb some of the kinetic energy when impacted by fragments.Through a comparative analysis using simulations and experiments,the impact resistance performance of unfurnished,aluminum oxide ceramic,and silicon carbide ceramic protected structures was examined.The results demonstrate that the addition of a silicon carbide ceramic protective structure reduces the peak pressure on the explosive in the fuze by 82.6%and decreases the witness plate’s dent diameter by 4.8%under fragment impact.These values surpass the performance of aluminum oxide ceramic protection,which exhibited reductions of 81.8%and 2.58%,respectively.Ceramic protection effectively enhances the fuze’s resistance to fragment impact,with silicon carbide ceramic outperforming aluminum oxide ceramic in impact resistance.
