The shape optimization design of the guide plate of the modular AUV recovery device

At present, the main method of ocean exploration is Autonomous Underwater Vehicle (AUV) in cooperation with manned Vehicles. After AUV completes its mission, it relies on the operator to retrieve it on the deck of the Vehicle. This recycling method has shortcomings such as low work efficiency and high personnel risk. In order to meet the development needs of AUV applications in the future, it is urgent to carry out research on AUV independent recycling technology. In this paper, a modular AUV autonomous recovery device based on the Unmanned Surface Vehicle (USV) platform is designed in conjunction with the SEA-KET autonomous AUV recovery method. In order to improve the success rate and efficiency of AUV docking, reduce recovery time, and optimize the collision force in the docking process, the guide plate in the recovery device is optimized and designed. The shape of the guide plate is obtained by combination optimization, and the guiding ability of the optimized guide plate is compared with the conventional shape guide plate, which verifies the validity and reliability of the optimization result
