深水滑翔机器人耐压壳体结构优化设计

Optimal design of the pressure hull structure of a deep sea glider

针对深水滑翔机器人耐压壳体在深水中压缩变形和海水密度随水深增大而变化等因素造成驱动浮力变化问题,利用压缩变形和密度变化对驱动浮力影响的互补特性,归纳了载体耐压壳体结构优化设计方法。保证耐压壳体抗压条件和质量最小前提下采用结构优化设计方法,降低耐压壳体压缩变形和海水密度变化对驱动浮力的影响,提高系统能源的利用率。

It is a key problem that the density changes in the ocean water mass and hull compressibility resulting from depth changes in the o- cean cause corresponding changes in net buoyancy of the glider and increase extra energy for glider gliding. In order to reduce the impact on changes of the net buoyancy and save energy consumption of the glider, a method has been proposed in this paper by optimal design of the pressure hull.
