Tire Uniformity Improvement Through Identification of Process Harmonics from Static Balance Measurements

摘要

Systems and methods for improving tire uniformity using estimates of process harmonic magnitude(s) from static balance measurements for a set of tires are provided. In particular, a sequence of observed magnitudes of static balance can be obtained for a set of tires. The sequence of observed magnitudes can be analyzed in conjunction with a baseline magnitude pattern associated with the process harmonic to derive a magnitude of the process harmonic. The magnitude of the process harmonic can be used to improve the uniformity of tires.

1. A method for improving the uniformity of a tire using static balance measurements for a set of a plurality of tires, comprising:
identifying at least one candidate process effect; obtaining a sequence of observed magnitudes for the set of tires, the sequence of observed magnitudes comprising a magnitude of static balance for each tire in the set of tires; obtaining a baseline magnitude pattern associated with the candidate process effect, the baseline magnitude pattern comprising a baseline magnitude of static balance for each tire in the set of tires; determining, with a computing device, a magnitude of a process harmonic associated with the candidate process effect based at least in part on the sequence of observed magnitudes and the baseline magnitude pattern; and modifying tire manufacture based at least in part on the magnitude of the process harmonic.
