摘要
文中利用AUTODYN-2D有限元分析软件,分别对不同锥角的药型罩形成射流侵彻钢靶板过程进行了数值模拟和对比分析。结果表明:在一定范围内,有利炸高随药型罩锥角角度的增加而增加,侵彻深度随药型罩锥角增加而减小。此结论与文献[1]得到的结论相吻合,验证了该数值仿真模型的正确性。
The numerical simulation and contrast analyses were conducted for the process of liner with different cone angle formed jet and penetrated target board by the software AUTODYN-2D.The results show that in a certain range,the profitable burst height is improved and the penetration depth becomes reduced with increase of shaped charge liner cone angle.This result is consistent with reference[1],and the correctness of numerical simulation model is proved.
