Cost considerations make it advantageous to use commercial data processing equipment in military applications such as mobile survivable systems. In order for this concept to be feasible, the commercial equipment must be able to withstand harsh shock and vibration environments. To determine the severity of these environments, SDRC performed an analysis of the vibration response of commercial electronic components mounted in a commercial cabinet rack, hard-mounted to a standard shelter, and subjected to rough terrain mobility and air transport loads. Using various modeling tools and techniques, finite element and dynamic system models of the shelter and cabinet were developed and forcing functions determined. Finally, modifications to the flexible cabinets to reduce loads on the electronic components were investigated.
