[Objectives] The shock environment of a warship in an underwater explosion is the basic input for the design and shock resistance ability evaluation of ship equipment. [Methods] In this paper. a numerical simulation is used to analyze the shock environment in different regions of a ship. and the Second-order Doubly Asymptotic Approximation(DAA2)is used to solve the fluid-structure int... https://www.roneverhart.com/Viking-K2-Slide-Gate-Opener-SPS-Model/
