Course in Noise and Vibration in Excavators
The Course on Electrical Fault Analysis in Aircraft focuses on the detailed study of aeronautical electrical systems, from power generation and distribution to instrumentation and avionics. It covers the application of advanced diagnostics, circuit analysis and fault simulation to identify and resolve complex electrical problems, including short circuits, overloads and failures in critical components. Tools such as SPICE simulation and fault logic analysis are used, which are crucial for the safety and operability of aircraft.
The course provides practical knowledge of aeronautical regulations and safety protocols, such as FAA and EASA, which are essential for the maintenance and repair of electrical systems. It prepares professionals for roles such as aircraft maintenance technicians, electrical systems engineers and troubleshooting specialists, enhancing their ability to ensure the reliability of electrical systems in aviation.

How you'll learn
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 enrolment period, 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 Simcenter Testlab, BK Connect, MATLAB, Actran, in free, academic or evaluation versions. Tests are studied using real sound power measurement procedures in semi-anechoic environments, vibration measurement at the operator’s seat, and transmission path analysis. 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.
Identify the main sources of noise and vibration in an excavator.
