Engine To Dynamometer Coupling — Torsional Vibration Considerations 841134

Couplings used for connecting engines to dynamometers can be subjected to torsional loads exceeding the design point unless precautions are implemented. The manufacturer's guidelines cannot alone predict a successful installation. A survey of the problems and solutions, as they apply to the modern high MEP engines, is presented. A wide range of testing speeds is possible with the appropriate combination of engine, coupling and dynamometer. The calculation of resonance conditions and practical guide for the selection and operation of a test set-up are presented.
