摘要
采用正交多狭缝扫描技术对复合装药在偏心起爆条件下爆轰波形进行测量。通过分析两个互相垂直方向上的五狭缝扫描迹线的几何关系,获得了爆轰波在狭缝交点处的传播速度及方向,并结合定向汇聚爆轰波形传播过程图,分析了其爆轰波的传播特性。结果表明,受内、外层装药爆速差的影响,爆轰波在传播过程中呈弧形状向内收敛,最终形成喇叭形波形,且沿中心线的爆速提高了约1.67 mm·μs-1。
In order to study the detonation wave propagation characteristics of composite charge under eccentric initiation, the det- onation wave was measured by the orthogonal multi-slit scanning technology. By analyzing geometric relation of multi-slits scan- ning traces from two mutually perpendicular directions, the detonation wave propagation velocity and direction at the intersection of multi-slits were obtained. Moreover, combined with the propagation process map of directional convergent detonation wave, the propagation characteristic of detonation wave was investigated. Results show that because of the difference between inner and outer charging detonation velocity, the detonation wave propagation is in an arc shape in the process of convergence inside, then forms a horn shaped wave, and the detonation velocity along the centerline increases by about1.67 mm·μs-1.
