How you'll learn
Fully 100% online training on the SEIUM campus, with downloadable material, recorded classes and a dedicated technical tutor. There are no fixed timetables: students progress at their own pace within the intake, which makes it possible to combine study with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Simcenter Testlab, Romax Enduro, Simcenter 3D, Ansys Fluent, MATLAB, in free, academic or evaluation versions. Tests are studied through real procedures: order analysis of gear noise on a semi-anechoic test bench, experimental modal analysis of a reducer housing, and CFD simulation of splash lubrication. Assessment is continuous across modules, 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.
Identify the sources of noise and vibration in electric transmissions.
Optimise gear microgeometry to reduce transmission error.
Analyse the structural dynamics and acoustic radiation of housings.
Measure and analyse noise using standardised techniques and order analysis.
Select lubricating fluids compatible with electrical systems.
