Modeling of Composite Hydrogen Storage Cylinders Using Finite Element Analysis

摘要

Pressurized hydrogen storage cylinders are critical components of hydrogen transportation systems. Composite cylinders have pressure/thermal relief devices that are activated in case of an emergency. The difficulty in accurately analyzing the behavior of a filament would composite storage cylinder derives from continually varying orientation of the fibers. In the proposed research, a finite element model will be developed to perform thermo-mechanical analysis of storage cylinders. Optimization of design variable such as cylinder size, type of liner, fiber orientation, thickness of the various layers, and location of the pressure relief device will be performed.
