Abstract

The radar stabilized platform is used to isolate the loader movement and keep the radar relatively stable. The modal analysis of stabilized platform could provide proof for modification and optimization of structure dynamics. The 3D model of novel external rotor stabilized platform is built by Pro-E. The finite element model is built by Ansys after the 3D model is simplified. The modal of platform is analyzed through finite element theory and Ansys software. And the natural frequency and vibration catalog of the eighth modal for stabilized platform is acquired. The modal of different grids and different materials are compared. It provides references for like analysis. And it also provides proof for optimization of stabilized platform. The program is designed to improve dynamic performance of stabilized platform.
