Abstract
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 modified method for balancing crank-shafts by using the soft-pedestal machines. The modified influence coefficient 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 Also, the decomposition method for irremovable masses has been replaced by an iteration method based on an influence coefficient approach. Furthermore, the validity and accuracy of the modified approach are verified in balancing practical crank-shafts.
