摘要
多点偏心起爆后,爆轰波相互作用在定向区域内产生了马赫波超压,使得该区域破片速度产生增益。利用爆轰波反射理论,建立多点偏心起爆后爆轰波相互作用特性的理论模型,并确定定向区内破片速度的增益特性。3种不同起爆方式的仿真计算和静爆试验结果对比表明,定向区内不同起爆方式得到的破片增益程度较为吻合。
After multi-spots off axis initiation, the action of detonation orientation area, so the velocity of fragments in orientation area gains. The mach wave in of detonation of detonation wave produces academic model wave action characteristic after multi-spots off-axis initiation is constructed by reflect theory wave, and the gain characteristic of fragment velocity in orientation area is confirmed. Emulation result of different initiation mode tallies with experiment result.
