Abstract: A method of using the repeated impact machine to simulate the process of hard target penetration is proposed for the physical simulation experiment of hard target penetration fuze. The layer-count algorithm of hard target penetration fuze is introduced. The feasibility of simulating the penetration acceleration signal by use of the impact process is discussed. A simulation experimental system is designed, and a layer-count detonating experiment is done using a certain type of penetration fuze. The result is compared with shooting range test curve, proving the feasibility of the simulation experimental methods. The accuracy of fuze burst point control method can be comprehensively tested. The reliability of fuze moving parts can be testified. Further research is needed as the shock acceleration peak is low and the shock interval is long.
