Abstract

Abstract

To overcome the high-risk and low-efficiency problems in large-volume ammunition fragmentation tests, a new method was proposed by setting water walls in front of target plates for comprehensively collecting the damage parameters of the fragments. The dynamic simulation software AUTODYN was used to simulate the penetration processes of the fragments into the target plates with the water walls and without the water walls. The influences of the thickness of the water wall and the incident angle of the fragment on the penetration capability was analyzed, and the effectiveness of the proposed method was verified by the test. The calculation results show that compared with the target plates without the water walls, the target plates with the water walls can greatly reduce the penetration capability of fragments. The results are also in good agreement with the test data, which indicates that it is feasible to use the target plates with the water walls to collect the damage parameters of the fragments in the actual tests.
