Abstract:

A finite element model of composite overwrapped pressure vessels(COPV)is es— tablished by ANSYS finite element software．In the modeling process，the number of filament wind— ing layers is treated as composite laminates with thickness and wrap ande variations of every unidi— rectional layer in the domes section considered．Using this model，static deformation analyses are conducted at several operating modes．Based on the maximum strain criteria，burst pressure of the vessel is predicted．The analyses results are compared with the test ones．The method of COPV rood— cling and analyzing are validated．
