To validate the feasibility of high-speed ignition by detonation and find out the ignition mechanism, an experimental system was developed for the investigation of detonation ignition with an in-line explosive initiator. The pressure changes in the test facilities after ignition at specific charges were measured by this system. The ignition delay time was achieved 0. 3 ms by the ignition method. The characteristics of powder burning and the attentions in practical applications were obtained by the way of ignition, such as the structure strength of the test facilities close to the explosion spot, the attenuation course of detonation wave and so on. The mechanism of the high-speed ignition by detonation was analyzed. The investigated results can provide help for applying the ignition by detonation to engineering.%为了验证采用爆轰可迅速引燃点火药进而引燃主装药的可行性及掌握此种点火方式下的点火情况,建立了火药装药系统下直列式起爆器爆轰点火实验系统.在特定装药条件下,对点火后实验装置内压力变化情况进行了测量,得出采用爆轰点火方式可以实现点火延迟时间为0.3 ms的目标,以及得出此种点火方式下,火药燃烧特点及实际应用时的注意事项,如起爆点处装置结构强度、爆轰波衰减过程等.分析了爆轰快速点火机理,为爆轰点火实际应用提供参考.
