Modal Analysis and Optimization of Some Internal Rotor Radar Stabilized Platform

The radar stabilized platform is the key part of radar supporting. It is used to isolate the loader movement and keep the radar relatively stable. The 3D model is built by Pro-E to aid the design of some internal rotor radar stabilized platform. 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 mesh 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.
