This dataset collects full-process data generated during the research project, covering structural crash safety analysis and fluid-structure coupling analysis of high-speed train bodies, as well as strength, stiffness and modal analysis of high-speed train bogies. Its core collected contents include the open-source fluid solver Su2, computational models for high-speed train body crashes and bogies, as well as post-solution result files. The purpose of this dataset is to conduct application verification for self-developed explicit finite element contact collision algorithms (including point-to-surface and surface-to-surface contact), the self-developed implicit solver for stiffness, strength and modal analysis, and the integrated fluid-structure coupling solving function, using high-speed train engineering calculation cases. Experimental results demonstrate that both the self-developed explicit and implicit solvers outperform mainstream commercial software in terms of computational efficiency, with all errors within the allowable range. This dataset provides strong support for the verification of prototype system development, and offers an application demonstration for efficient parallel CAE analysis throughout the full life cycle of design and development for typical components of new-generation high-speed trains.
