Structure and Test of a Magnesium Alloy Pressure-Resistant Cabin

Abstract:

Based on the military engineering applications of magnesium alloys and structure feature of light-weighting pressure-resistant cabin, this paper puts forward that foundry magnesium alloy may be applied to pressure-resistant cabin structure of the unmanned underwater vehicle(UUV). Selecting and using ZM5 casting magnesium alloy, typical structure test specimen of the water pressure-resistant cabin with thin-walled structure was designed and fabricated. Under the different outside hydraulic pressures, structure stresses and distortions of the specimen and it’s sealing performance were tested and measured. The test data and result show that the structure intensity and rigidity satisfy requirements, pressure-resistant structure and wedged-ring connection and also sealing performance stabilize. This experiment study establishes a foundation for magnesium alloy application research on the water pressure-resistant cabin structure of UUV.
