Abstract

Based on the ANSYS software, a finite element model using for analyzing the properties of the developed cryogenic composite overwrapped pressure vessels (COPV) is established. The stress and strain conditions under the operational pressure were analyzed including of the overwrapped fibrous layer and the metal inside lining, which were used to respectively explain the properties under the normal temperature and the low temperature. The differences between the normal temperature properties and the low temperature properties were also clarified. Simultaneously, the weakness of the cryogenic COPV was identified. A test apparatus applying for the experimental studies of the developed cryogenic COPV was build, the pressure-circulation experiments under the normal temperature and the temperature of liquid nitrogen were respectively carried out, and the actual service requirements of the developed cryogenic COPV were tested.
