FCV High-Pressure Hydrogen Container FEM ASU/FrontCOMP V6

Support the generation and analysis of FEM mesoscale models for Type-IV pressure vessels for FCV applications, achieving detailed analysis evaluations that cannot be reproduced with axisymmetric models.

Fuel Cell Vehicles (FCVs) are expected to provide clean and sustainable mobility with zero emissions, enabling rapid refueling and long-distance travel through the use of hydrogen. The tanks designed to safely carry 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 containers 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 layer modeled from the liner and fiber bundles of a Type-IV pressure vessel 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, reducing the licensing costs for large-scale computation. In version 6, parallelization of the model generation process has been implemented, significantly shortening the generation time.
