Rotating discs balancing

Abstract EN

In this paper, a single plane balancing method based on vibration amplitude readings only, has been adopted.

This method is discussed in detail, including an analytical basis and a practical implementation procedure.

Four runs of trial mass are required to determine the vibration amplitudes when a calibration mass of fixed value is placed in four different positions, each position being advanced (900 ) from its previous position.

An experimental test rig is built and prepared to obtain the vibration measurements necessary to be fed as an input data to a written computer program, which calculates the magnitude and location of the weight required to balance the test rig rotor the.

For the present study, the adopted method was successful and permitting safe operation for the rotor disc through its running speed.
