dc.description.abstract	In order to better control speed of the electric motor-driven ID Fan, the existing fluid coupling was replaced with avariable speed drive, but this led to two failures of the motor shaft and coupling. The drivetrain was instrumented tomeasure bearing vibration, transient torque, and speed during various operating conditions. Testing of thedrivetrain highlighted that the excitation source was likely a structural resonance, with the greatest amplitudesoccurring on the bearing pedestals. A new elastomeric coupling was designed and tuned for the drivetrain,reducing torsional vibration by 80%.
