为缩短聚能装药设计周期,提出了一种根据射流参数计算单锥角药型罩几何尺寸的反演设计方法。该方法利用射流成型理论建立了药型罩和射流参数之间的非线性方程组,给定射流头尾速度和长度,可求解得到单锥角药型罩的半锥角、口径和壁厚值。运用AUTODYN-2D软件对反演得到的药型罩进行射流成型仿真,结果表明:仿真得到的射流与给定的射流参数值偏差在工程许用范围之内,表明此反演设计法可以有效的指导单锥角药型罩的设计。

An inverse design method of simple cone liner based on the velocity of jet head and tail and jet length was presented in order to shorten the design cycle of the shaped charge. The half cone angle, liner diameter and cavity liner thickness can be calculated by the method based on the nonlinear equations of theory of jet formation contact with the liner parameters and shaped charge jet parameters. The condition of simple cone liner obtained by inverse calculation formed was simulated through AUTODYN-2D. The results show that the jet parameters acquired through simulation are in agreement with the jet parameters used in inverse design calculation. The inverse design method can be used in the simple cone liner design.
