Multi-point initiation explosively formed projectile(EFP) charges with different N (the number of initiation points), D_I (the diameter of annular initiation), L_C/D_C (the length/diameter of charge) were studied by LS-DYNA program. program The influences of multi-point initiation charge configuration parameters, such as N, D_I, L_C/D_C, on the formation parameters of EFP with fins were studied. The results of numerical simulation indicate that there are remarkable effects of N, D_I and L_C/D_C on the formation parameters, including v, L_E/D_E (the length/diameter), W_S/D_E (the wingspan/diameter) of EFP with fins. The number of fins is equal to the number of initiation points. When the N is 4, the W_S/D_E of EFP with fins approaches the maximum. Increasing D_I and L_C/D_C effectively enhances the v and L_E/D_E of EFP with fins. The formation parameters of EFPs formed by hemispherical liner with uniform or variational wall-thickness were compared. Results indicate that hemispherical liner with variational wall-thickness is a more feasible option. When N=4, D_I=40 mm, and L_C/D_C=0.8 respectively, EFP with more appropriate configuration can be approached.
