摘 要:为了优化爆轰波定向战斗部的性能,研究了不同的偏心起爆形式。利用试验验证过的流体动力学仿真模型研究了偏心一线起爆不同起爆点数、偏心两线不同夹角和偏心三线不同夹角等对战斗部破片速度、飞散的影响。结果表明:对于本研究对象,在一条起爆线上布置4个起爆点是足够的;对于偏心两线起爆,两线之间夹角60°可在定向侧产生最高的速度增益,达38.37%;同样对于偏心三线起爆,夹角45°时的破片速度增益最大,达39.36%。定向方向的破片速度增益是爆轰到破片的传播距离(时间)和爆轰压力共同作用的结果。To optimize the performance of the detonation wave aiming warhead, the different forms of asymmetrical initiations were studied. The fluid dynamic simulation model verified by experiment was used to research the effects of asymmetrical one initiation line with different initiation points, a- symmetrical two initiation lines with different central angles, and the asymmetrical three initiation lines with different central angles of the adjacent lines on warhead fragment velocity and scattering. The results show that for the researched object ,4 initiation points are adequate in one initiation line; in the asymmetrical two lines initiation, the central angle of 60° may produce the highest velocity enhancement 38.37% in the aiming direction side, so do the asymmetrical three initiation lines with central angle of 45°,with an enhancement of 39.36%. The velocity enhancement of the fragments in the aiming direction is the interacting results of detonation transfer length (time) and the detonation pressure.
