To analyze the dispersion characteristics of axial prefabricated fragment warhead,the fragment velocity and scattering angle under single-point initiation in center of the warhead and multi-point initiation were simulated by LS-DYNA software,and experimental verification was carried out.Obtained the influence laws of the characteristic parameters of fragment velocity and scattering angle under single-point initiation in the center of the warhead and the multi-point initiation.The result shows that:compared with the single-point initiation,multi-point initiation can improve the velocity of fragment,when initiation points increases,the fragment velocity keeps increasing in the first place,then tends to be stabilized.When the initiation points increase from 2 to 6,the fragment velocity increased by 21.1% .As the initiation point continues to increase,the velocity does not increase,the number of initiation points has little effect on the scattering angle.
