摘要

起爆方式对爆炸成型多定向破片(MDF)战斗部的形成过程和形态具有重要影响。在深刻理解MDF战斗部爆炸成型机理的基础上,通过对药型罩由切割网栅形成多个破片过程的仿真和爆轰波作用理论分析,研究了环起爆方式下起爆环半径对MDF战斗部参数的影响。研究表明:随着起爆环半径的增加,切割药型罩形成的MDF头部破片速度随之增大,但破片的剩余质量将会减小,而破片的发散角则随起爆环半径的增加呈现先增大再减小的趋势;对于特定的MDF战斗部,当起爆环半径在8~12 mm时,破片的侵彻能力和对目标的毁伤作用效果最好。

Abstract

Initiation methods affect the formation and morphology of multiple directional fragments (MDF) warhead greatly. Based on the explosively forming mechanism, the effect of annular initiation radius on the fragment formation is analyzed by simulating the process of the liner from the incisory cover to fragments. The results show it the annular initiation radius is bigger, the MDF tip fragments increase quickly but the residual mass decrease gradually; the radial dispersion angle increases firstly and then decreases; for a certain MDF warhead, if the annular initiation radius is between 8 mm and 12 mm, the fragments penetration and damage effect are the best.
