Finite Element Analysis of the Blast Response of a Complete Shelter System and Effects of Equipment Rack Model Modifications.

Abstract

The transient blast response of an Army S-280 shelter containing electronic equipment racks was obtained with the NASTRAN finite element code. Results using a model of the complete shelter-rack system in a tie-down condition are compared with results obtained with a simpler model consisting of the front wall and front racks. Modifications are made to the finite element model of the rack. Comparisons are made between the NASTRAN responses and data obtained from the DIAL PACK field test for accelerations and shock spectra on the front wall and front rack.
