  • In order to solve the issues of high cost and large risk factor of ammunition explosion in the battlefield damage test, the method of dimensional analysis is used to analyze the establishment method of cylindrical ammunition similar models. The explosive power field relationship between different similar models and an original model is studied. The AUTODYN finite element simulation software is used to simulate the explosive power field, and the effectiveness of the similar models is verified by real-experiment data. The results show that the simulated results are consistent with the results of both the dimensional analysis and the actual tests. Therefore, in the actual test, the similar model can be used instead of the original model. This study provides a theoretical basis for the use of the ammunition similar model in battlefield damage test and has certain engineering value.
