Patent ID: 8359921

Claim:
A method to balance a wheel assembly having a first balance corrective plane and a second balance corrective plane, comprising the steps of: selecting predetermined discrete sizes of balance weights for all available candidate corrective balance weights; measuring the wheel assembly for an imbalance; and balancing the assembly, comprising the steps of: creating a first multiplicity of the candidate corrective balance weights for the first balance corrective plane and a second multiplicity of the candidate corrective balance weights for the second balance corrective plane; creating a multiplicity of pair-wise combinations of the candidate corrective balance weights by selecting one candidate corrective balance weight from the first multiplicity and one candidate corrective balance weight from the second multiplicity of the candidate corrective balance weights for multiplicity of all possible pair-wise combinations of selections, said pair-wise combinations including one candidate corrective balance weight each from the first multiplicity of the candidate corrective balance weights and the second multiplicity of the candidate corrective balance weights; evaluating the multiplicity of pair-wise combinations of the candidate corrective balance weights for minimization of couple and static forces and couple and static balance residuals; selecting a unitary corrective pair-wise combination of corrective balance weights from the multiplicity of pair-wise combinations of the candidate corrective balance weights based on the step of evaluating the multiplicity of pair-wise combinations; affixing the selected first corrective balance weight from the first multiplicity of the unitary corrective pair-wise combination of corrective balance weights to the assembly at the first corrective plane; and affixing the selected second corrective balance weight from the second multiplicity of the unitary corrective pair-wise combination of corrective balance weights to the assembly at the second corrective plane.
