NUCLEAR WEAPONS EFFECTS ON SHIPBOARD ELECTRONIC SYSTEMS Contract No. NObsr 85266 Index No. SFOI30U05, Task 1775 VOLUME 2 Analysis of Antenna Structures for Blast Loading

摘要

Shipboard radar antennas, vital and vulnerable parts of the electronic system, are completely exposed to environmental loading when installed in the customary locations on the ship. In the event of a nuclear attack, it is possible that dynamic stresses experienced by structural members of the antenna will greatly exceed stresses caused by the most severe hurricane winds. Stress intensity resulting from wind loading is usually approximated as a steady state condition that is independent of structural response;dynamic stresses resulting from weapon effects depend upon the vibrational response of the structure.
