Abstract
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.
