摘要: 运用平面爆轰驱动理论计算大锥角装药的药型罩加速过程,再结合射流分析理论,建立了大锥角聚能射流理论计算方法,并编制了射流分析程序ASCC(Analytical Shaped Charge Code)。通过与实验、数值模拟计算结果的比较,说明该方法是可行的,可以有效地计算大锥角罩的射流参数。Abstract: An analytical model for liner collapse and jet formation in shaped charge with wide cone angle is described. The basis of this model is planar detonation driving theory and PER jet formation theory. Based on this model an analytic shaped charge code (ASCC) is programmed and then used to calculated jet velocity gradient and diameter versus time for shaped charge with wide cone angle. Good agreement has been found between the experimental and the numerical results.
