射孔弹聚能射流侵彻钢靶的数值仿真与实验分析OA北大核心CSTPCD
Numerical Simulation and Experimental Analysis of Shaped Charge Jet Penetrating into Steel Target
应用ANSYS/LS-DYNA3D显式非线性有限元软件,采用ALE多物质算法对某型石油射孔弹装药结构下聚能射流形成、侵彻钢靶过程进行了数值模拟及分析,并与实验数据作了对比.结果表明,数值仿真与实验结果均值间的穿深误差为8.31％,孔径误差为15.16％,这完全满足设计需要,为今后数值计算在射孔弹装药结构优化设计方面的应用提供了参考依据.
Based on the three-dimensional explicit nonlinear FEM software ANSYS/LS-DYNA3D, the numerical simulation and analysis were conducted for the process of a kind of shaped charge jet formation and penetrating steel target with the ALE method. Contrast analysis was made between the simulation results and experiment data. The results show the relative computational error from average experimental data is 8.31% in penetration depth, 15. 16% in perforation diameter…查看全部>>
