Abstract

The invention provides an AUV underwater recovery fluid power test experiment device applied to a pool laboratory. An underwater docking base station and the AUV are fixedly mounted with a cantileverbeam and a crossbeam respectively through a first rigid connecting rod and four third rigid connecting rods, the mounting mode is firm and reliable, and accurate experiment data measurement is not influenced. The crossbeam crossing two sides of the pool can move along a guide rail direction through driving wheels, the movement of the AUV in an underwater docking process is simulated, the speed ofthe AUV can be changed through changing the speed of the driving wheel, manual adjustment can be carried out in real time according to experiment requirements, and the experiment measurement range iswider; due to use of the first rigid connecting rod and the crossbeam, the position and the attitude of the AUV can be adjusted, the AUV can thus perform underwater docking experiment data measurementat different attack angles and different sideslip angles, and the application range of the experiment device in the invention is wider.

Description

technical field [0001] The invention relates to the technical field of AUV underwater performance testing, in particular to an AUV underwater recovery hydrodynamic testing experimental device applied to a pool laboratory. Background technique [0002] With the continuous expansion of the area of ​​human development and utilization of marine resources, the exploration of deep sea and open sea is increasing, which requires AUV to have the ability to work in deep sea and open sea. However, due to the limited endurance and underwater operation time of AUVs, in order to realize long-distance, large-depth, and long-term continuous underwater operations of AUVs, it is necessary to connect AUVs with underwater docking base stations for energy replenishment, data uploading, and task Downloads etc. work. [0003] During the autonomous docking process between the AUV and the underwater docking base station, the flow field around the AUV will be affected by the underwater docking base ...
