Abstract:

设计了一种双锥药型罩与双向装药结构相结合的聚能射孔弹模型,通过数值模拟方法研究其射流成型机理,并计算其射流参数。结果显示:双锥药型罩的小锥角部分形成聚能射流,大锥角部分形成翻转弹丸,射流头部和弹丸的速度分别为6250m/s和1620.9m/s,弹丸长度和平均直径分别为26.1mm和8.6mm。结合数值模拟结果,对射流侵彻公式进行了修正,并利用修正公式预测该射孔弹侵彻钢靶的深度,计算结果为69.6mm。最后,按照该模型进行侵彻实验,实验回收弹丸的长度和平均直径分别为28.1mm和8.8mm,侵彻钢靶的深度和孔径分别为70mm和17mm。实验表明:数值模拟与理论计算方法相结合是可行的,能够有效地计算射孔弹的射流参数并预测其侵彻深度;该射孔弹侵彻性能优越。
