【 摘 要 】

Munroe effect has been more and more used in blasting engineering and most assembling energy technologies use a shaped charge device. In this paper, a new method is used to achieve detonation wave collision by detonating cord initiation system. A numerical simulation using LS-DYNA on detonation wave propagation and collision process caused by different initiation forms is implemented. Numerical results show that peak pressure by this new method can reach 2.42 times than the traditional method, and the growth of specific impulse at the explosive bottom is 49% compared to early results. Based on this numerical simulation, an experiment of explosive-determination of power be implemented, the experiment result can verify the simulation result well.
