Modal analysis and optimization of the internal rotor radar stabilized platform
摘要
为了更好地设计某型内转子光电雷达稳定平台, 运用Pro-E软件对其进行了三维实体建模, 合理简化后, 进入Ansys软件建立有限元模型。应用有限元理论和Ansys软件对该平台进行了模态分析, 得到稳定平台前八阶模态的固有频率和振型。其中对比了不同网格、不同材料产生的不同模态, 对同类分析提供了参考, 也为此稳定平台的设计优化提供了依据, 提出了改善该平台结构动态性能的措施。
Abstract
The internal rotor radar stabilized platform is desigened. The 3D model of the internal rotor radar 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 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.
