Vehicle–track–bridge interaction · Flexible bodies · Stress recovery and fatigue
Find railway vehicle and flexible-body tutorials by learning goal, then follow a route through the existing Simpack, Abaqus and Ansys material.
194 video lessons · 772 subtitle files · 193 lessons with all four subtitle files. No accompanying subtitle files: s05-e001 — 0-课程效果.
Choose a learning route: Simpack basics · Abaqus flexible track · Stress recovery and fatigue
Current access: the repository is public. Readers can browse the catalogue and download the existing published Release videos and subtitles without repository membership. Use the recorded lesson links; public access does not grant a blanket reuse licence.
Shortest viewing steps: find a lesson in its series catalogue, open an existing local MP4 or download it from the series Release, then select the matching Chinese or English SRT in a player that supports external subtitles. Start with the usage guide. The library currently has no embedded player, dedicated search interface or automatic learning-progress tracking.
Feedback: correction and contribution instructions explain how to report a lesson ID, timestamp and observed problem. Public issues are readable without repository membership; creating an issue requires GitHub sign-in.

Tutorial recordings; accompanying model files and software versions are not confirmed, and independent numerical validation is not established. Documentation is available in eight languages; subtitles remain Chinese and English.
Open a series title for the existing lesson-by-lesson index. Published Release pages contain the downloadable video and subtitle assets. The original series identifiers are retained; there is no Series 4.
For a first vehicle model, start with Simpack basics and Series 6. For flexible-track workflows, choose the Abaqus route in Series 1 or the Ansys route in Series 3. Continue with Series 5, 7 or 8 for vehicle–track–bridge models. Use stress recovery and fatigue in Series 2 when that is your focus. This is an editorial learning suggestion, not a verified prerequisite chain.
The topic groups below organise the supplied lesson titles. They are not evidence that a model, numerical result or software-version combination has been independently validated.
- Flexible rail and spring-supported floating slab modelling in Abaqus; FBI generation
- FTR authoring and flexible-track setup in Simpack
- Wheelset, bogie-frame and complete-vehicle modelling; vehicle–floating-slab coupling
- TRE / PSD excitation, flexible-body animation and response post-processing
Series 2 — Dynamic Stress, Strain and Fatigue Analysis of Flexible Bodies with Ansys/Abaqus, Simpack and fe-safe
- Abaqus / Ansys interface preparation and FBI flexible-body generation

Open the relevant series, choose a lesson and reuse an existing local MP4 when available. Otherwise, download its MP4 together with the matching .zh-CN.srt or .en.srt file from the series Release. Keep the stable filename stem unchanged and select the subtitle file in your local video player. VTT files are available as an alternative format. A repository clone or the Code → Download ZIP archive does not include the video assets stored in Releases; their absence from a clone does not indicate missing media. The four subtitle formats are absent for s05-e001.
Download links follow the repository’s access settings. While the repository is private, an authorised GitHub account is required. Video links are download links, not a promise of an embedded streaming player.
The introduction and topic guide are provided in English, Simplified Chinese, Japanese, French, German, Italian, Spanish and Korean. This is documentation localisation: it does not create additional subtitle tracks or dubbed audio. The current subtitle languages are Chinese and English. Original Chinese lesson titles remain available for exact identification.
This is a tutorial library, not a validated benchmark or a software distribution. A topic appearing in a recording does not imply that its model files, solver licences or input data are included. Verify the software version, units, boundary conditions, damping, model reduction settings and evaluation criteria before adapting a workflow. Historical discussions of railway standards must not be treated as statements of current requirements. Beam–Solid and Beam–Beam name two course tracks; they do not establish which modelling level is more accurate.
Subtitle file presence and checksum agreement do not establish translation accuracy or audio–subtitle alignment. Technical translations should be checked against the original recording and the relevant software documentation.
Follow the contribution guide and report corrections with the series identifier, stable lesson identifier, subtitle language and timestamp where relevant. Keep original file identifiers unchanged when proposing a better title or translation. The public repository's issue forms are available to signed-in GitHub users. Do not upload commercial software, licence files, third-party course material or models without the necessary permission.
Repository maintenance, course authorship and software ownership are different roles. See the existing provenance statement for the recorded source and rights status. No official vendor affiliation or endorsement is claimed. Public availability alone is not a blanket licence to reuse or redistribute the course media.
