Support the generation and analysis of FEM meso-scale models for Type-IV pressure vessels for FCV vehicles, achieving detailed analytical evaluations that cannot be reproduced with axisymmetric models.
Fuel Cell Vehicles (FCVs) are expected to provide clean and sustainable mobility through the use of hydrogen, enabling rapid refueling and long-distance travel with zero emissions. The tanks designed to safely store high-pressure hydrogen are extremely important components for FCVs, but overcoming many challenging issues such as weight reduction and cost reduction is necessary for widespread adoption. ASU/FrontCOMP is an analytical tool developed for the design of high-pressure vessels for FCVs. ■ To reproduce the complex stress state within CFRP products, a mesoscale model that directly models the fiber bundle shape is required. ■ A 3D analysis model of the CFRP layers modeled from the liner and fiber bundles of Type-IV pressure vessels will be created within practical timeframes. ■ Detailed analysis using a fiber bundle embedding model and pseudo-mesoscale analysis using a fiber bundle mapped model are possible. An FEM analysis model that reproduces the design requirements of CFRP pressure vessels can be easily generated. The fiber bundle mapped model also supports input and output in FrontISTR (free) format, which can reduce the licensing costs for large-scale computation execution. In Ver.6, parallelization of the model generation process has been implemented, significantly shortening the generation time.

An FEM analysis model that reproduces the design requirements of CFRP pressure vessels can be easily generated.
