Shock Transmission, Response Calculation of a Compartment of a Frigate with Discrete Masses and Rayleigh Damping

Abstract

This report gives results as obtained with a finite element analysis using the finite element program DIANA of a compartment of a Frigate loaded with a shock pulse based on the kick-off velocity concept. Three decks are included in the FEM model. The effects of discrete masses, either fixed at the deck or mounted at discrete springs (with and without damping), Rayleigh damping and excitation of the hull have been analysed. Responses at the decks are compared with the standard pulse shapes as defined in the Shock Handbook, which are generally used to define the shock loading of the equipment. Both the kick-off pulse and the standard pulses are based on the same underwater explosion.
