How you'll learn
Fully 100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetables: students progress at their own pace within the intake, which makes it possible to combine the course with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is KISSsoft, Romax, MASTA, HBM nCode, MATLAB, in free, academic or evaluation versions. Tests are studied using real durability test procedures on transmission benches, oil and wear particle analysis, and examination of gear and bearing failures. Assessment is continuous by module plus the final integrating project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
Explain the fatigue mechanisms in gears, shafts and bearings of heavy-duty transmissions.
