Research on Modal Simulation and Experiment of a Radar Active Fixing-Board

Abstract

As a major force-bearing structure of Active Phased Array Radar, the Active Fixing-boards vibration characteristics should be investigated in the engineering design stage and the prototype stage. In this paper, Finite Element Method (FEM) is used for modal simulation and the detailed modal experiment is used to analyze the modal parameters of the first 6 modes. The results show that the modal parameters calculated by FEM agree well with those by modal experiment.
