How you'll learn
A 100% online programme on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so the programme fits around your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is SMI Advanced Spring Design, ANSYS Mechanical and MATLAB, in free, academic or evaluation versions. Testing is studied through real procedures: load-travel curves of progressive springs, fatigue testing of suspension springs and spring failure analysis. Assessment is continuous by module, plus the final project.
Standards covered: EN 13906-1, EN 10270-1, EN 10270-2, ISO 22705-1, ISO 26909, EN 15800 and SAE HS-795.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
