单体式无人航行器的设计、实验及优化
|
摘要
论文从实用性的角度出发,对单体式无人航行器的结构展开研究,旨在提供一种能够实现水面、水下巡航的载体形式。首先,提出一种能够实现水面、水下巡航的航行器设计方案。在该方案的基础上,基于模块化设计理念,将航行器分为头舱、能源舱、动力舱、控制舱四个模块,并进行详细设计。利用Finemarine对航行器的水动力性能进行分析,得到了航行器在水中保持持续稳定状态的条件。分析的结果可作为航行器部分结构优化和控制系统设计与实现的依据。通过制作样机和下水实验,还发现了该航行器尚存在运动性能欠佳的一些缺陷;最后,针对该航行器装配和实验过程中存在的不足,提出了优化设计方案,为结构改进提供了依据。
In order to provide a type of carrier which can cruise both on the surface of water and under water, the unmanned monohull vehicle is studied. A design scheme of the vehicle is presented, in which the vehicle is divided into four modules: head module, energy module, power module and control module. Hydrodynamic performance of the vehicle is analyzed with software Finemarine, and the condition keeping the vehicle in a steady state is gained. Through Manufacture and test of the prototype, it is found that there is some limitation in movement performance of the vehicle. An improvement scheme is proposed for structural design.
