Glossary of balancing technology
Level separation
Ability of a balancing machine to distribute the unbalance precisely to the correction planes and to minimize the correction plane influence ratio.
Eigenfunction, modal function
Describes the course of an eigenmode as a function of the rotor axial coordinate; function is normalized to a maximum value of one.
Single-plane balancing
Correction of the mass distribution of a rigid rotor in order to reduce the static residual unbalance to certain limit values.
Single-plane balancing machine
Balancing machine that uses gravity or centrifugal force to balance a rotor in one plane.
Setting up the machine mechanics
Work to adjust the mechanics of a balancing machine to the balancing of a rotor.
Setting the measuring device
Work to enter rotor and balancing-specific data into the measuring device of a balancing machine.
Electrical concentricity deviation
Systematic error of eddy current sensors during concentricity or shaft vibration measurement caused by residual magnetism or electrical irregularities of the measured part.
Sensitivity to imbalances
Measure of the change in the vibration of an (elastic) rotor due to a change in unbalance, expressed by the ratio between the change in the vibration vector and the change in the unbalance vector.
