Balanced rigid rotor with a suitable mass used to calibrate and check balancing machines. Test or calibration masses can be exactly and reproducibly attached.
Change of the unbalance condition of a rotor caused by temperature.
Difference between max. and min. value of the radii of a shaft's cross section with reference to a stationary rotational axis.
Mass with reasonable size, to evaluate the response of a rotor caused by an unbalance in a plane.
Final correction of small residual unbalances – typically with the rotor in its operational bearings.
A procedure by which the mass distribution of a rigid rotor is adjusted in two planes to ensure that the residual dynamic unbalance is within specified limits.
