Shock Reduction by Means of Resiliently Mounted Floors; Influence of Damping and Coinciding Eigen Frequencies (Schokreductie d.m.v. Zwevende Vloeren; Invloed Demping en Samenvallende Eigenfrequenties),

Abstract

The analysis concerns a simple 2D finite element model of a large resiliently mounted steel floor on a deck of a frigate subjected to the effects of UNDEX shock. For the prescribed motion at the deck edges, a kickoff pulse has been taken. The latter being obtained with the SWISS Code for an actual charge geometry. Cable wound shock mounts were installed. Shock response results were compared with those as obtained earlier for the same geometry. Stiffness of the middle deck was changed in order to study the effect of nearly coinciding eigen frequencies and the influence of damping was studied.
