Research Progress on Design,Monitoring and Failure Modes of Composite High-Pressure Gas Cylinders
Composite high-pressure gas cylinders have the characteristics of lightweight and high strength,designability,corrosion resistance,pressure bearing capacity.Therefore,they are broadly used in automobile,navigation and aerospace industries.In this paper,the research progress of design optimization,on-line monitoring and failure modes of composite high-pressure gas cylinders were discussed.The design optimization was mainly based on grid theory and finite element analysis,the on-line monitoring was mainly based on acoustic emission,ultrasonic guided wave and electromagnetic ultrasonic,and the failure modes were mainly blasting failure and fatigue failure.The continuous development and high demand in aerospace,navigation and automotive fields will promote the continuous development and innovation of the composite high-pressure gas cylinders,especially in the analysis and calculation,design optimization,damage and destruction.
