    Abstract
  • The concept of reliability design is introduced into torpedo structure design to rectify the insufficiencies of the conventional safety coefficient method. A safety margin equation and the solving approach of torpedo shell structural reliability based on a theoretical formula are proposed by combining the classic theory of torpedo shell and the second-order second-moment method. Simulation of torpedo shell structure by using the probabilistic design system(PDS) module in software ANSYS is performed to achieve its reliability. The proposed scheme combines structure design with reliability design, which may facilitate the design of torpedo shell.
