摘　　要：多旋翼无人机的飞速发展对稳定云台设备提出了更高的性能要求,使云台不断朝轻量化、小型化、模块化方向发展,但传统云台往往存在重量较重、减振性能不佳等问题,针对此问题设计一款单光学载荷三轴云台。首先介绍了云台的工作原理,其次对云台结构材料选型、各轴系结构设计和装配进行说明,最后利用ANSYS Workbench软件对云台结构进行了静力学校核和模态分析。研究结果表明:该云台结构稳定,满足强度和刚度使用要求,减振装置起到了良好的降频效果,降低了与多旋翼无人机激振频率产生共振的风险。The rapid development of multirotor unmaned aerial vehicles(UAVs) has imposed higher performance requirements on stabilized gimbal systems,leading to their evolution towards lightweight,miniaturization and modularization.However,traditional gimbals often have problems such as heavy weight and poor vibration reduction performance. To address this issue,a single optical payload three-axis gimbal has been designed. The working principle of the gimbal is first introduced,followed by an explanation of the material selection,the structural design of each axis and the assembly process.Finally,the static calibration and modal analysis of the gimbal structure are carried out by using ANSYS Workbench software.The results indicate that the gimbal structure is stable,meeting the requirements of strength and stiffness,and that the vibration damping device has a good frequency reduction effect,reducing the risk of resonance with the excitation frequencies of multirotor UAVs.
