Vibration and strain data were measured on a modified munitions trailer to ensure that the design strength criteria had not been exceeded. These data were used in conjunction with a computer model to determine if the stress levels were sufficiently low to allow adequate fatigue life without further modification to the trailer. By combining standard data verification techniques with a stress prediction technique, data from a number of channels were reviewed at the test site to determine the severity of measured levels. This information was used to control the test process.

This paper describes results of a planned comprehensive test program to identify the realistic dynamic environment commercial off-the-shelf (COTS) equipment will experience when utilized in Military Ground Mobile Command Control, Communication, Computer, and Intelligence (C4I) systems housed in DoD Standard Family Tactical Shelters. COTS equipment are generally designed for office use and lack robustness for military use in a ground mobile tactical environment. A realistic dynamic design criteria must be utilized for an appropriate mounting and/or isolation system design in the integration of a shelter. Acceleration spectral density functions are described to assist the designer in providing a COTS-based, survivable, cost-effective ground mobile tactical shelter-based C4I System.
