起爆方式对偏心式定向战斗部破片速度分布的影响研究

Research on the Distribution of Fragment Velocity of a Eccentric Initiation Warhead by Initiation Mode

为了揭示起爆方式对偏心式定向战斗部破片速度分布及增益的影响,文中运用数值模拟的方法对一端起爆、两端同时起爆和线起爆方式下偏心式定向战斗部的爆炸过程进行了研究。研究表明,两端两点同时起爆时破片的速度增益比中心起爆时高28.1%,且高速度破片在周向上的分布角度宽,为最优的起爆方式。

In order to reveal the influence of initiation mode on distribution and enhancement of fragment velocity, the numerical simulation of the explosion process of the eccentric initiation warhead under one end eccentric initiation, both ends eccentric initiation and eccentric line initiation were studied in this paper. The results show that the two points of both ends eccentric initiation＇s enhancement of fragment velocity is 28.1%0 higher than the center＇s, and the distribution angle of high-speed fragments is much wider on the circumference. So the former is the best initiation mode.
