Measurement Techniques Aims and scope

A method of determining the oscillation parameters of the elements of the rotating units of turbine-driven sets based on an analysis of variations in the characteristics of the output signals of a primary converter is described. Using as an example a newly designed approximate mathematical model, it is shown that it is theoretically possible to determine the oscillation parameters of the blades of turbomachines. A block diagram of a device for experimental testing of the proposed method is presented.
