摘要
为了研究炸药对爆轰临界直径的影响,建立了楔形和圆柱形装药的物理模型,采用LS-DYNA2D程序模拟了爆轰波传播过程,得到楔形和圆柱形装药的临界直径。模拟结果与文献基本符合,进一步说明了利用LS-DYNA程序对小尺寸装药爆轰波传播的数值模拟是可行的。
In order to research the effect of RDX explosive on the critical diameter of booster explosive, the physical models of wedged charge and cylindrical charge were set up. Using LS-DYNA2D program, the detonation transfer was numerical simulated, and the critical diameters of booster explosive of wedged charge and cylindrical charge were obtained. The simulation results accord with the reference literature, and it indicate that numerical simulation of effect of small size charge on detonation transfer by LS-DYNA program is feasible.
