In allusion to the situation of lack of in-depth research of long rod projectile penetrating aslant into concrete targets of different spacing, This article put forward the method of using ANSYS / LS-DYNA analysis software, and This article has made the simulation analysis of the process of the long rod projectile penetrating aslant into three-ply concretes targets of different spacing. This method can make up for former lack of theoretical analysis and experimental difficulties and other problems. Simulation results show that the characteristic rule obtained by the simulation has certain guide to the mastery of the penetration features of the long rod projectile penetrating aslant into concrete targets of different spacing, especially the changing rule of the speed and acceleration. This plays a very important role in the design of hard target smart fuze.
