Abstract

In this paper, the characteristics of explosion shock wave in the water shock tube are studied by means of finite element simulation analysis. The principle of the comparison calibration method based on the pre-pressure water shock tube device is introduced, and the propagation rule of the explosion shock wave in the infinite water area and the water shock tube is simulated by Autodyn finite element software. The simulation results are compared with the empirical formula of the underwater explosion shock wave, and the corresponding similarity analysis of the shock wave pressure waveform is performed. The research results show that the water shock tube can generate a quasi-δ pulse signal with larger peak pressure at the end surface under the condition that the explosive mass is very small. In addition, when the length-diameter (L/D) ratio of the water shock tube is greater than 16, the quasi-δ pulse signal can be guaranteed to be a stable plane wave and has higher similarity with the shock wave pressure under the actual underwater explosion condition.
