Engineering　design　course　is　renowned　for　its　abstraction　and　complexity,　which　can　have　an　impact　on　the　quality　of　classroom　instruction.　To　address　this　issue,　this　study　has　undertaken　the　design　and　development　of　an　E-learning　software　utilizing　simulation　technology　and　the　C#　programming　language.　With　a　focus　on　the　challenging　topic　of　torsion　resistance　coefficient,　a　3D　model　of　the　gearbox　shaft　was　established,　and　simulation　calculations　were　used　to　obtain　digital　resources　such　as　Mises　stress　plots.　Leveraging　these　resources,　an　E-learning　software　was　created,　garnering　widespread　recognition　with　a　high　approval　rate　of　92.86%　among　students.　This　software　effectively　utilizes　digital　resources　to　aid　students　in　comprehending　abstract　concepts　and　significantly　enhances　their　enthusiasm　for　learning.　The　findings　of　this　research　contribute　to　the　field　of　E-learning　and　provide　valuable　references　for　future　design　and　development　of　engineering　design　case　studies.　©　2024　Copyright　held　by　the　owner/author(s).
