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.
