摘　　要：通过对水下机器人的主体外形以及传统水下机器人的外附体进行建模,运用CFD流体软件对其进行仿真分析,发现自主水下航行器外附体中,天线产生阻力最大。天线是自主水下航行器必不可少的通信模块。针对天线带来的大阻力问题,设计出两种折叠天线机构。运用ADAMS软件对比了两种折叠天线机构运动性能参数;运用SolidWorks的应力仿真模块分析了折叠天线各个部分的耐压强度。结果表明折叠天线的应用能为自主水下航行器性能产生积极影响,为自主水下航行器的设计提供参考。The main body shape and external body of the traditional autonomous underwater vehicle are modeled and analyzed by CFD software.It is found that the antenna has the largest resistance in the external body of the autonomous underwater vehicle.The antenna is an indispensable communication module for autonomous underwater vehicles.Aiming at the problem of large resistance caused by antenna,two folding antenna mechanism is designed in this paper.Comparison of the performance parameters of two folded antenna mechanisms using ADAMS software.The compressive strength of each part of the folded antenna is analyzed by using the stress simulation module of SolidWorks.The results show that the application of the folded antenna can positively affect the performance of the autonomous underwater vehicle,and provide reference for the design of the autonomous underwater vehicle.
