Structural Modeling and Response of Command, Control and Communication Shelter Systems for Event DICE THROW

摘要

Structural finite element models of the Army command, control, and communication systems AN/TRC-117, AN/TRC-110, AN/TCC-61 which utilizes the S-280 shelter, and the AN/TRC-145 and AN/GRC-142B, which utilize the S-250 shelter, were developed for NASTRAN. Loading models and dynamic response for overpressure levels experienced in the recent DICE THROW field test were determined for all but the AN/GRC-142B. Comparisons between measured and analytical accelerations are given for the AN/TRC-117 and the AN/TRC-145 at an incident overpressure level of 41.4 kPa. The comparisons were generally poor for the AN/TRC-117 but much more favorable for the AN/TRC-145.
