Modal Analysis of the 72 Inch TAC-4 Ruggedized Rack (CLIN 0003AA)

摘要

The finite element modeling and subsequent static and modal analyses of the 72inch TAC-4 Rugged Rack computer system (CLIN 0003AA), as designed by Science Applications International Corporation (SAIC), has been performed to determine the natural frequencies and corresponding mode shapes for subsequent transient shock analysis. This rack is designed to allow incorporation of commercial-off-the-shelf (COTS) computer systems for naval tactical computing requirements while still meeting applicable shock and vibration mil-specs.
