US 2016/0238487 A1 · Tire Uniformity Improvement Through Modified Sampling of Uniformity Parameters

Abstract

Methods and systems for improving tire uniformity through identification of uniformity attributes, such as process harmonics are provided. More particularly, uniformity measurements acquired according to a non-uniform sampling pattern can be obtained and analyzed to estimate one or more process harmonics (e.g. the magnitude of the process harmonic). The non-uniform sampling pattern can specify the acquisition of uniformity measurements in a varying or irregular manner about one or more revolutions of the tire. For instance, the non-uniform sampling pattern can specify a random spacing between data points. The uniformity attributes estimated from the uniformity measurements can be used to modify the manufacture of tires to improve tire uniformity.

Dependent claims

A method of improving the uniformity of a tire, comprising:

identifying a non-uniform sampling pattern for measuring a uniformity parameter for one or more tires, the non-uniform sampling pattern having a plurality of data points;
obtaining a plurality of uniformity measurements for the one or more tires, the plurality of uniformity measurements acquired according to the non-uniform sampling pattern;
