摘　　要：在分析圆柱形装药侧壁比冲量分布以及装药直径对端面比冲量影响的基础上,提出采用比冲量分布曲线的补差曲线装药,即根据轴向比冲量分布调整不同位置装药直径的方法来产生等爆轰场强。并通过数值模拟和原理样机试验对其可行性进行研究。结果表明,采用比冲量分布曲线的补差曲线装药可使炸药轴向表面比冲量基本一致,对破片形成等爆轰场强作用;由于采用了曲线装药结构,实现了战斗部轴向能量增益,提高了破片初速。Through the analysis on distribution of specific impulse acting on lateral wall for cylindrical charge and relationship between charge diameter and specific impulse acting on end wall,this paper presents that producing equal explosive field intensity in axial by adjusting charger diameter,that is,adopting charge curve which is complementary to specific impulse curve.And the reliability of this design have proved by numerical simulation and prototype tets.The results indicate that axial specific impulse of charger surface is basically identical because of adopting suitable charge curve,which can form equal explosive field intensity effect on fragments,and fragments＇ initial velocity increase due to axial energy gain.
