Advanced Machinery Dynamics

In order to put the 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
