Review of Torsional Vibration Measurement Methods

Torsional vibrations are unwanted phenomena induced by varying torque in power transmission systems. This paper reviewed the various types of torsional vibration measurement systems, that being strain gauges, accelerometers, Laser Doppler Vibrometers (LDV), optical sensors, and its forms of signal generation using zebra tapes and encoder disks to chart the current state of technology available for torsional vibration measurement. The advantages and disadvantages of each method were discussed to promote further research in the unexplored gaps of these measurement systems and to indicate the viability of each method for practical industrial applications.
