Abstract

Abstract

In order to explore the influence of different charge mass ratios of tandem charges on the power of underwater explosion, theoretical analysis was carried out according to the empirical formula of underwater shock wave, and the underwater explosion power of different charge mass ratios of tandem charges is numerically simulated. Under the same charge mass condition, the impulse of explosion output and the damage effect on the target structure are compared and analyzed with different charge mass ratio of tandem charges and single charge. The results showed that the total charge was 400 g TNT, the underwater explosive power of tandem charges structure is obviously better than that of single charge, and the explosive power of tandem charges structure increases with the increase of the charge ratio.When the charge mass ratio ratio η was 1∶1, the impulse gain and the deflection of the target plate are the largest, the impulse gain was increased by 27.43% and the deflection of the target plate was increased by 23.58%. The experimental results of small charge showed good agreement with the theoretical analysis and numerical simulation results.
