ABSTRACT

Three new booster pellets were designed based on the shock initiation, effective charge, and shock wave convergence theories in order to improve the initiation capacity of the booster pellet. The initiation capacities of the three new booster pellet configurations were studied by numerical simulation using the ANSYS/LY-DYNA software. The results show that the initiation capacities of the three booster pellets are powerful. The output pressure of booster pellet III is better than that of booster pellet II and the output pressure of booster pellet II is better than that of booster pellet I. The output pressure of booster pellet II is affected by the cavity radius.
