大曲率半径药型罩的数值模拟

The Numerical Simulation of Liner with Big Curvature Radius

采用数值模拟技术对爆炸成型弹丸(EFP)的成形过程进行了计算分析,通过药型罩材料的选择,在大曲率半径结构参数下对 EFP 的成形性能进行了研究。模拟结果表明不同材料药型罩对 EFP 成形性能有较大影响,并且该结果能够和试验得出的结果达成较好的一致。

Calculation and analysis of explosive formed projectile(EFP) s shaped procedure was developed by numerical simulation.The performance of EFP was studied in the condition of big curvature radius parameter,with the select of liner s material.The outcome of simulation indicates that there is some great influence on shaped performance of EFP from different material.And the outcome can get favourable accordance with the outcome of experiment.
