Rotating Machinery Dynamics Seminar

More than ever, the engineering of rotating equipment is under pressure to deliver better performance with reduced noise/vibration and increased durability.

This free seminar can help you answer questions like:

  • What is an order? How does it get measured?
  • What is torsional vibration? What type of problems does it cause, and how can they be solved?
  • How can viewing data in the angle domain, rather than time domain, give me insight into problems?
  • What kinds of unique problems do gears and bearings have? How can they be analyzed and solved?
  • What unique frequency signatures are generated by electric motors?
  • What issues do hydraulic pumps show?

In this free seminar, both simulation and test methods will be presented in an interactive, side-by-side format.


Order analysis and tracking

  • What is an order? How is it calculated?
  • How are orders measured, simulated and interpreted?
  • Review of orders generated by common equipment
Torsional vibration
  • What is torsional vibration?
  • How are torsional vibrations measured and analyzed?
  • Resonances, drivelines, engines and other examples
  • Lumped parameter models of torsional vibration
  • Gear transmission error
  • Gear sideband orders: eccentric gears and offset rotation
  • Bearing frequencies: inner race, outer race, fundamental train frequency
  • Bearing faults and envelope analysis
  • Hydraulic pump basics
  • Cavitation
Electric motors
  • AC and DC motors
  • Computation orders
  • Switching frequencies and PWM controllers
  • Imbalance: mass versus speed effects
  • Influence coefficients
  • Shaft centerline plots
Angle domain processing
  • Angle versus time data
  • Viewing data in degrees, revolutions or cycles
  • Examples of angle domain analysis: piston slap, pilot ignition, etc.
Resonances - What is a resonance? How is it identified?
  • Operational deflection shapes
  • CAE and test correlation
