Analysis of the Response of Shipboard Array Antenna under Various Shock Environments
Through theoretical calaulation and finite element simulation,the response of shipboard array antenna under different shock environments is studied.The force-bearing model of the shipboard array antenna under exploding impact is simplified to a multi-DOF system with base excitation,and the response under various exploding environment are calculated by applying virtual constraint boundary method to the multi-DOF system.The results show that spectral acceleration has little impact on equipment re-sponse,while spectral displacement and spectral velocity have great influence on it.Analysis results are a good reference for analy-sis of the response and anti-shocking ability of shipboard electronic equipment under shock environment.
