    摘要
  • 摘要: 转板是光电雷达稳定平台的关键元件之一。为了更好地设计和分析某光电雷达稳定平台的转板，运用ProE软件对其进行三维实体建模，合理简化后，进入Ansys软件界面建立有限元模型。应用有限元理论和Ansys软件对其进行动态特性分析，得到了转板前八阶模态的固有频率和振型，以及要求范围内的谐响应。对比了不同方法划分网格的网格质量，采取不同材料得到了不同模态。分析结果表明：设计的转板在关心的频段0~50 Hz，2 000 Hz~8 000 Hz内不发生共振，符合设计要求。
    Abstract: Gimbal is one of the key elements of the electro-optic radar stabilized platform. The 3D model of the gimbal in electo-optic radar stabilized platform was built by Pro-E, and the finite element model was built by Ansys after the simplification of the 3D model. The dynamic characteristics of the gimbal were analyzed through finite element theory and Ansys. Different mesh generations of model were compared. The 8-order modal natural frequencies and vibration modes of the gimbals with different materials were obtained, and the harmonic response was analyzed. Results show that the gimbal doesn-t resonate at 0~50Hz, 2 000Hz~8 000Hz， which meets the design requirments.
