Transient Response Analysis of the 72 Inch TAC-4 Ruggedized Shipboard Rack Subjected to an Underwater Explosion Event

Abstract

The finite element modeling and subsequent transient analysis of the 72 Inch TAC-4 Rugged Rack computer system (configurations 0001AA and 0003AA only), currently employed in U.S. Navy shipboard applications, has been performed to determine the system's response to simulated shock inputs. This rack is designed to allow incorporation of commercial off the shelf (COTS) computer systems for naval tactical computing requirements while still meeting MIL-STD-901D, the applicable shock specification. By showing the viability of this computer simulation of the shock response of the current TAC-4 rack system, an argument for a lessening of the actual physical testing requirements for acceptance of future TAC systems can be made.
