    Abstract
  • To calculate the volume of underwater explosive power field of three-dimensional model simply and accurately, this paper proposes a calculation method for quickly estimating simulation results based on the function of AUTODYN software that the one-dimensional results can be mapped to three-dimensional models. In this method, the underwater explosive power field boundary is synthesized into a circle, which approximates an array sphere, and the computational cost is reduced. Compared with the data from SolidWorks modeling, it is concluded that this method can estimate the size of underwater explosion power field of the three-dimensional model according to the radial dimension of cross section of the power field, and the power field formed by the underwater explosion shock waves at the same time is not affected by the shock wave interaction. This research may provide reference for simplifying simulation calculation of underwater array and effectively defending warship against torpedo attack.
