为研究装药在偏心起爆条件下的爆轰波传播特性,采用正交多狭缝扫描技术对装药表面的爆轰波传播过程进行观测,从两个垂直方向同时记录了多条扫描迹线,通过对实验结果进行分析,获得了爆轰波在狭缝交点处的传播速度及方向,并绘出了定向区域的波形演变图。结果表明,正交多狭缝扫描技术能够较全面地记录装药偏心起爆时爆轰波传播过程的信息,可以为爆轰波传播特性及波形变化规律的研究提供依据。

For study on detonation wave characteristics of charge under off-axis multi-spot initiation, the orthogonal slits scanning technology was used to observe propagation process of detonation wave on the surface of charge. Multiple scanning traces were recorded for both orthogonal directions. The propagation speed and direction of detonation wave in the intersection points of the slits was obtained by analyzing the traces, and evolution program diagram of waveform in aimed direction was drawn. The obtained results indicate that the orthogonal slits scanning technology can record the information of detonation wave process under off-axis multi-spots initiation more thoroughly. Furthermore, the technology can provide adequate evidence for analyzing the propagation characteristics and waveform evolution of detonation wave.
