摘要
采用 LS-DYNA3D 对爆炸成型弹丸(EFP)的成型过程进行了数值模拟.其模拟结果与实验数据基本一致。通过数值模拟分析了装药长径比 L/D 对 EFP 动能的影响并对有关数据进行了拟合,得出了装药长径比和 EFP 动能之间的关系式,对 EFP 设计具有实际意义。
The process of EFP s formation is simulated using LS-DYNA3D,The result of simulation basically accords with the data of experiment,In addition,how the slenderness ratio(L/D)of explosive influences the kinetic energy of EFP is wtudied.,Finally the relation between the slenderness ratio(L/D) of explosive and the kinetic energy of EFP is educed.To some extent ,it is instructing for the design of EFP.
