摘要
本文提出了一种准一维拉氏分析方法,用二维拉氏实验方法测得的不同拉氏位置上的压力和径向位移的变化曲线作为输入量,就能求解二维冲击波起爆过程中对称轴附近的流场。作为初步应用,文中列出了在两种加载条件下,压装TNT的二维冲击波起爆过程的分析结果。
In this paper, a quasi - one - dimensional Lagrangian analysis method is presaent-ed. This method with the profiles of the pressure and the radial displacement at different Lagrangian positions, which determined from the two -dimensional (2-D) Lagrangian experimental technique for the input, can be used to solve the flow field near the axis of a 2- D shock initiation process. As a preliminary application, we show the analysing results of 2- D shock initiation process in pressed TNT at two loading conditions.
