摘要：

Numerical simulation for the initiation or ignition of explosive with at: luminum shell was carried out following the Lee-Tarver initiation model of the Autodyn-3D code. Three types of fragments ( including spherical, cylindrical and cubical shape) were used respectively to impact the explosive in the project. The influence on charge ignition of the shape and velocity of fragments was analyzed. By means of the "up-down" method, the critical ignition velocity for Octol explosive was given out.
