摘　　要：针对一种变锥度结构的大型破片式战斗部,采用数值仿真的方法,对战斗部预制破片的飞散速度和飞散角度等特性进行研究,并通过地面静爆试验对仿真计算结果进行验证,结果表明变锥度结构的破片战斗部在增大飞散角方面有明显优势,可有效提高战斗部的杀伤威力。A large fragmentation warhead with variable taper structure was investigated, in which the prefabricated fragments flight characteristics such as scatter velocity and scatter angle were numerically simulated. The static-explosion test result agreed with the numerical simulation result. The investigation indicated that the fragmentation warhead with variable taper structure has superiority in increasing the scatter angle, therefore the killing power will be improved obviously.
