Abstract: A 70MPa hydrogen environment fatigue test system has been designed and applied in the manufacture of a hydrogen storage vessel. Key equipment is the 80MPa flat steel ribbon wound high pressure hydrogen storage vessel. A reasonable stress distribution has been realized, that is low stress in the liner of the pressure vessel and even stress in the flat ribbon layers. This optimal stress distribution is achieved through the adjustment of the prestress in flat steel ribbons. A control system for the fatigue test system has also been designed. It consists of a double control model, i.e. manual control and automatic control, to satisfy different experimental requirements. The system is the unique one that can be used in the real hydrogen environmental fatigue test system in China. An experiment for the 70MPa onboard composite material hydrogen vessel has been carried out on the system. The experimental result from this test is in close agreement with the practical operating conditions.
