Optimization of composite cylinder compressibility for deep sea exploration
Abstract
This study aims to design and manufacture composite pressure vessels with optimized compressibility to reduce the energy consumption of submarines to depths down to 6000 meters. An innovative methodology based on genetic algorithms was employed to design tailored composite cylinders with enhanced compressibility. Two types of cylinders were produced using filament winding: one with a conventional [±55°] winding sequence commonly used in marine applications, and another with an optimized sequence generated by a genetic algorithm. The manufacturing process and final quality were carefully examined before proceeding to the design stage. Once the cylinders' quality was validated, static tests were conducted in hyperbaric pressure vessels until implosion. The results showed that both sequences achieved comparable implosion pressures, while significantly different compressibilities were attained by varying the winding sequence, demonstrating the potential of genetic algorithms for optimizing compressibility. Finite element analysis was then used to evaluate strain variations under hydrostatic pressure, and calculated compressibilities were compared with measured values. The results confirm that the proposed methodology enables the optimization of composite cylinder compressibility for deep-sea applications through tailored winding sequences.
