A modified approach based on influence coefficient method for balancing crank-shafts

The conventional balancing machines utilize two-plane separation for the de termination of equivalent imbalances. However, the imbalance masses of a cr ank-shaft cannot be corrected at arbitrary locations of the balancing plane s. This study has presented a modified method for balancing crank-shafts by using the soft-pedestal machines. The modified influence coefficient metho d for asymmetrical rotor-bearing systems has been applied to balance crank- shafts. Also, the decomposition method for irremovable masses has been repl aced by an iteration method based on an influence coefficient approach. Fur thermore, the validity and accuracy of the modified approach are verified i n balancing practical crank-shafts. (C) 2000 Academic Press.
