【 摘 要 】

As a new type of underwater glider with many advantages, the disk-underwater glider has been widely used in recent years. The hydraulic buoyancy control system, the attitude control system and the steering control system must be installed inside the pressure housing, therefore, as for the design of the pressure shell, the minimum weight and the maximum effective volume are the important technical indicators. In order to adapt to the saucer appearance of the glider, the pressure resistant structure designed in this paper is a ball - ring - ring pressure resistant structure. Through the ladder finite element numerical simulation, under the premise of ensuring enough strength and rigidity of the pressure bearing shell, we gradually improve the structure of the pressure hull, in order to achieve the design goal of light weight, enough strength and large volume.
