Abstract: In this paper, a layer-by-layer updating modeling method for filament-wound hydrogen storage cylinder based on 3D laser scanning system and ABAQUS is presented. By programming in Python, the geometric data obtained from the 3D scanner are fitted by non-uniform Rational B spline, and combined with the winding angle generated by the winding software to generate the finite element model in ABAQUS. The validity of the finite element model was verified by comparing the results of hydraulic blasting test with Hashin criterion, and the failure mechanism of filament-wound hydrogen storage cylinders was explored. The results show that, the blasting pressure and strain response predicted by the finite element model are within 5% of the test results, and the predicted blasting location and failure mode are consistent with the test results.
