In order to put theory into practice, this training includes real-life demonstrations and 25 case studies.

Rotor modeling for machine diagnostics – identify design parameters that determine rotor dynamic behavior – understand the relationship between critical speeds, resonances and natural frequencies
Anisotropy – recognize machine behavior due to support stiffness anisotropy
Machine balancing – differentiate between balancing methods such as influence vectors, static/coupled, and polar (modal) – learn about balancing for the thermal bow effect
Rotor-to-stator rubs – detect machine rubs – uncover how rub condition can show fractional frequency – differentiate between the different types of variable bow effects
Bearing design (fluid bearings and magnetic bearings)
Diagnose and mitigation of fluid induced instabilities.
Shaft cracks – discover symptoms related to shaft crack diagnosis – uncover relationship between cracks, thermal sensitivity and rotor radial vibration
Gear forces analysis – recognize pros and cons of different gear types – understand normal gear force directions – calculate five discrete gear frequencies
Torsional vibration measurements and analysis – learn about torsional excitations and the importance of torsional calculations – measure torsional vibration using Time Interval Measurement (TIM) and other methods
Impact testing and analysis – understand the difference between operating deflection shape (ODS) and mode shape analysis – use impact testing to identify component natural frequencies
Signal processing – understand the importance of sampling – convert an analog signal to a digital format
