✦ Synopsis

The conventional balancing machines utilize two-plane separation for the determination of equivalent imbalances. However, the imbalance masses of a crank-shaft cannot be corrected at arbitrary locations of the balancing planes. This study has presented a modi"ed method for balancing crank-shafts by using the soft-pedestal machines. The modi"ed in#uence coe$cient method for asymmetrical rotor-bearing systems has been applied to balance crank-shafts. Also, the decomposition method for irremovable masses has been replaced by an iteration method based on an in#uence coe$cient approach. Furthermore, the validity and accuracy of the modi"ed approach are veri"ed in balancing practical crank-shafts.
