摘要

For a double-deck cylindrical shell with rib reinforcement which is a typical structure of the submarine shell, the dynamic respond process of the structure subjected to short range explosion of the explosive charge in deep water was simulated by virtue of the finite element method, and the rules of bubble change, water media motion and shell deformation were obtained. According to the simulation result above, the dynamic respond and damage characteristics of the shell are analyzed with the action of shock wave and water jet. The achievements can be of important reference for the safety analysis of submarine shell and the evaluation of damage effect.
