摘要

Deep Sea Vehicles (DSVs) play a crucial role in deep-sea exploration, surveying, and research, with their operational viability in high-pressure environments hinging on material composition, design, and functionality. This study analyzes the pressure hull strength, stability, and material properties of Ocean-Gate's Titan, a submersible used for Titanic exploration. A Computational Fluid Dynamics (CFD) analysis of Titan's outer body is conducted to assess its performance across varying velocities and depths. Additionally, a structural and implosion analysis of Titan’s pressure hull will evaluate its behavior at depths of up to 4000 m. Unlike the original composite material, this study proposes the use of titanium for the pressure hull, hypothesizing enhanced strength and reliability. The analysis suggests that using titanium could have mitigated the risk of fatal incidents. By comparing the performance and failure modes of different materials, this research underscores the importance of material selection in the design and safety of DSVs, aiming to provide insights for improving future submersible designs and ensuring safer deep-sea missions.
