In this work, a laser torsional vibrameter was used to measure the torsion vibration of a rotating shaft system under electrical network impact. Based on the principles of laser Doppler velocimetry, the laser torsional vibrometer (LTV) are non-contact measurement of torsional oscillation of rotating shafts, offering significant advantages over conventional techniques. Furthermore, a highly complex...
An Electromechanical transient process caused by power system failure or changes of operating conditions may lead to shaft torsional vibration of turbo-generator unit. A laser torsional vibrometer was used to measure the torsion vibration of a rotating shaft system under electrical network impact. The laser torsional vibrometer are non-contact measurement of torsional oscillation of rotating shafts,...
