Optimization Design of Pressure Hull for Long-Range Underwater Glider Based on Energy Consumption Constraints

Underwater gliders are a class of ocean observation equipment driven by buoyancy, and their energy consumption source is mainly generated the active regulation buoyancy. The periodic elastic deformation pressure hull during upward downward movement underwater glider can have large impact on its driving This paper relates optimization problem with glider, improvement factor taken as objective. Based mechanical theory, theoretical model constraint derived. A hybrid genetic simulated annealing algorithm (HGSAA) adopted to optimize developed Huazhong University Science Technology (HUST). Additionally, effectiveness optimized mathematical results were verified tests. sea trial show that after optimization, buoyancy unit decreased 21.9%, total carried increased 12.4%.
