Abstract: Through theoretical calculation 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 response, while spectral displacement and spectral velocity have great influence on it. Analysis results are a good reference for analysis of the response and anti-shocking ability of shipboard electronic equipment under shock environment.
