High-Speed Magnetic Bearing Test Stand

High-Speed Magnetic Bearing Test StandThis test stand was custom designed to perform a wide range of experimental research in rotor-bearing dynamics, control and diagnostics. The configuration of the test rig (Fig. 5) provides ability for development and testing of different strategies for controlling rotor vibration, development of control-oriented modeling and design techniques for rotordynamical systems, and study of the new diagnostic techniques based on magnetic bearing actuation and support. The Magnetic Bearing Test Stand consists of:

  • 2 radial magnetic bearings with sensors (12lbf)
  • 1 thrust magnetic bearing (27lbf)
  • 2 exciter bearings (1/2 of the magnetic bearing capacity)
  • 3 different shaft sizes:
  • 1/2" dia ´ 12"
  • 1/2" dia ´ 25"
  • 3/8" dia´ 25"
  • brush type motor (15,000RPM, 48VDC)
  • 3 movable balance disks: 1" thick and two 1/2" thick
  • 4 touchdown bearings (deep groove ball bearings)
  • 2 fully digital 5-axis controllers (one for motor and bearings, another one for exciters)
Bently Nevada Rotor Test Rig

Bently Nevada Rotor Test RigThe Bently Nevada Rotor Kit is a versatile and compact model of a rotating machine which enable to simulate several categories of lateral shaft vibration by duplicating vibration-producing phenomena found in large rotor-bearing systems, e.g., fluid-film bearing oil whirl/whip, loose rotating parts, mass unbalance, shaft bow, etc. Various vibration characteristics may be observed by changing:

  • rotor speed
  • shaft bow
  • rotor stiffness
  • amount and angle of unbalance
  • rotor-bearing relationships

The test rig can also be used to study experimental identification techniques for rotor-bearing systems, and to verify the theoretical modeling predictions.

Rotordynamic Rub Facility

Rotordynamic Rub FacilityThe unique test rig is used to study the high-speed, multi-plane (annular and/or point) rubbing phenomena in rotating machinery and its effect on the rotor dynamic behavior. The test rig include the following:

  • 30in long 3/4" diameter shaft
  • two high precision roller element bearings
  • 12,000 RPM max speed
  • Motor and speed controller (±2% accuracy on RPM, 110VAC 60Hz)
  • 2 pair x-y probes (4 probes total)
  • 2 annular rub generators (radial) with rub switch mechanisms
  • 2 single point rub generators (radial)
  • 2 automatic balancers
  • 2 rotor mass wheels
  • 2 bearing blocks holding Sorbothane washer
  • perturbator device
  • torque transducer
Stirling Laboratory Research Engine (SLRE)

Stirling Lab Reseach EngineThe SLRE is designed and fabricated as:

  • Horizontally-opposed, two piston, single-acting engine
  • Split crankshaft drive mechanism
  • Photo-electric sensor is used to sense top dead center and a shaft angle encoder is used to trigger data acquisition
  • The engine can be electric motor-driven and, thus, can run as a cooler This facility was completely qualified via a research grant from the Ohio Aerospace Institute (OAI) and utilized by CSU graduate students.
