Study and Design of Coupling Shafts Between Engine and Dynamometer 2004-28-0001

In testing of engines in engine test bed, the engine is connected to dynamometer through a solid shaft. The shaft connecting engine and dynamometer can have the problems of torsional vibrations, whirling of shafts and vibration of engine and dynamometer.
The frequently encountered problem is resonance in torsional vibration leading to excessive vibration of the coupling shaft. This vibration can lead to the catastrophic failure of the shaft.
This paper deals in designing of shaft with right stiffness and dampening. This involves theoretical calculation of resonance frequency of torsional vibration and measurement of shaft and coupling stiffness.
