为了提高水下航行器的航行时间和距离，本文提供一种长航程AUV的折叠天线方案。通过机械结构设计、机构运动学分析及机构物理参数的选定，实现AUV天线的折叠。通过减少水下航行器在航行时的涉水附体，进而降低水下航行器的航行阻力；通过设计关键部位的密封，实现整体机构在水下能正常工作，并通过打压实验验证密封方案可行。
In order to improve the navigation time and distance of underwater vehicles, a long-range AUV folding antenna solution is provided. Through mechanical structure design, mechanism kinematics analysis and mechanism physical parameter selection, the folding of AUV antenna is realized. By reducing the wading appendages of the underwater vehicle during navigation, the navigation resistance of the underwater vehicle is reduced; by designing the seals of key parts, the whole mechanism can work normally under water, and the sealing scheme is verified by the suppression experiment.
