摘要
研究不同形状破片在穿甲过程中,速度、动能变化曲线有着重要意义。以钨破片为研究对象,采用ANSYS/LS-DYNA有限元计算方法,对比分析球形、立方形、圆柱形钨破片穿甲速度、动能衰减曲线。结果表明:立方形钨破片速度、动能衰减最大,对后效毁伤效能有较大影响。该研究结论可对战斗部威力设计、破片研制提供一定参考依据。
It is significant to study the velocity and kinetic energy curve in armor piercing process of different shapes fragment. Taking tungsten fragments as the research object, analyzing the attenuation curve of velocity and kinetic energy of spherical, cubic and cylindrical tungsten fragments penetrating armor plate by using the ANSYS/LS-DYNA finite element analysis software. Research shows that the velocity and kinetic energy of cubic tungsten fragments has the most attenuation, which would has a great influence on the after damage effect. The research conclusion is the basis of the power of warhead design and fragments production.
