Study on the Titanium Film in the Pressure Self-Adaptive Water-Tight Junction Box of Underwater Vehicle

Abstract

Water-tight junction box (WJB) is one of key underwater vehicle technologies, which is indispensible in nowadays underwater engineering. Taking the advantage of large deformation range and corrosion resistance characters of the titanium material, this paper utilizes the titanium thin film material to put forward a titanium film pressure adaptive compensator (TFPAC) which solves the pressure problem and improves the reliability of the WJB greatly. The finite element analysis (FEA) software ANSYS is used to analyze the stress and strain condition of the titanium film when the film is suffering the internal pressure in the working condition. The feasibility and reliability of the Pressure Self-adaptive Water-tight Junction Box (PSAWJB) is tested and verified by hyperbaric chamber tests.
