摘要
为了探讨爆轰快速点火的特性,依据工程应用的实际情况,利用直列式起爆器设计了直列式爆轰点火器及实验装置,并进行了相关实验研究.结合实验装置的特殊结构,建立了直列式爆轰点火器起爆过程的理论计算模型,应用4阶龙格-库塔法编程计算得出爆轰冲击波在实验装置内传播过程中各物性参数的变化规律,并结合实验测试结果进行了分析.结果表明,在直列式爆轰点火结构设计中,利用突扩截面可以显著衰减冲击波的强度,减弱对点火过程的影响,有利于装药的全面、瞬时点火.
In order to study the characteristics of high speed ignition by detonation,in-line detonation igniter and test installation were designed with in-line explosive initiator,and experimental study was carried out according to the actual conditions of engineering application.The theoretical calculation model of detonation process of in-line explosive initiator was set up based on the special structure of test facilities used in the experiment.The main parameters of blast wave were calculated by programming language with 4-step Runge-Kutta when it propagated in the test installation,and experimental results were analyzed.The conclusion indicates that blast wave can be attenuated by divergent cross section,which can weaken the influence on ignition and make for general and instantaneous ignition.
