摘要： Methods and systems for improving the uniformity of a tire are provided. More particularly, one or more parameters of a measurement process harmonic contributing to uniformity measurements performed for a tire can be identified. The measurement process harmonic can be a process harmonic effect associated with the acquisition of uniformity measurements of a tire, such as a process harmonic effect associated out-of-roundness of a road wheel used to load a tire during uniformity measurement in a uniformity measurement machine. The measurement process harmonic can result solely from the acquisition of uniformity measurements and may not contribute to actual tire non-uniformity. Once identified, the one or more parameters associated with the measurement process harmonic can be used to correct the uniformity measurements of the tire to account for the measurement process harmonic. Tire manufacture can then be modified to improve tire uniformity based on the corrected measurements.

摘要： Systems and methods for improving the uniformity of a tire by separating uniformity contributions associated discrete effects, such as effects resulting from product joints, from continuous effects are provided. For instance, uniformity contributions associated with the product joints are determined by analyzing a uniformity waveform to process the uniformity waveform into one or more continuous components and at least one joint component. Knowledge of the uniformity contributions associated with product joints in the tire can be used, for instance, to make structural improvements in the manufacture of the tire, to actively manage the joint-making process, and to perform dynamic correction of joint effects.

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.

摘要： Systems and methods for improving the uniformity of a tire using convolution/deconvolution-based uniformity parameter estimates of a tire are provided. For instance, convolution can be used to estimate radial force variation from one or more uniformity parameter measurements, including radial run out parameter measurements. Deconvolution can be used to estimate radial run out from one or more uniformity parameter measurements, including radial force variation parameter measurements. The estimated uniformity parameter can be estimated from the uniformity parameter measurements using one or more models. The one or more models can represent an estimated radial uniformity parameter at a discrete measurement point as a weighted sum of the measured radial uniformity parameter at the discrete measurement point and one or more selected measurement points proximate the discrete measurement point. The measurement points can be selected based on the contact patch length of the tire.

摘要： A system and related method for improving tire uniformity includes providing a number (n) of test tires manufactured in a known order and identifying at least one candidate cyclic process effect with a corresponding frequency of introduction (f). A given uniformity parameter, such as radial or lateral run-out, balance, mass variation, radial lateral or tangential force variation, is measured for each tire in the test set, and measured data points are combined into a concatenated composite waveform. At least one process harmonic associated with each identified cyclic process effect is separated from the tire harmonics, for example, by Fourier transformation with identification of the process harmonics as positive integer multiples of the mth harmonic of the measured uniformity parameter where m=n/f. Once the process harmonics are extracted, filtered uniformity measurements can be provided or new tires can be built with the process effect minimized.

摘要： Methods and systems for improving the uniformity of a tire are provided. More particularly, a magnitude of a uniformity parameter can be obtained for each tire in a set of a plurality of tires. The magnitudes associated with the set of tires can be transformed according to a probability distribution function (e.g. a Weibull distribution function) to obtain a set of transformed magnitudes. Parameters associated with a probability distribution function can be estimated based at least in part on the transformed magnitudes. Parameters associated with the probability distribution function can be used to determine data indicative of a measurement error in the uniformity measurements attributable to a measurement process harmonic. The data indicative of the measurement error can be used to correct uniformity measurements obtained for tires and to modify tire manufacture based at least in part on the corrected measurements.

摘要： Methods and systems for improving the uniformity of a tire are provided. More specifically, one or more characteristics of a composite uniformity parameter can be determined from uniformity summary data (e.g. uniformity vectors) associated with a plurality of harmonics of the composite uniformity parameter. For instance, a peak to peak range of a composite uniformity parameter and/or a distribution of amplitudes of a composite uniformity parameter for a set of tires can be determined from uniformity vectors associated with selected harmonics of the composite uniformity parameter. According to example aspects of the present disclosure, the one or more characteristics of the composite uniformity parameter can be determined using multivariate normal distributions (e.g. bivariate normal distributions) of the uniformity summary data. Once identified, the one or more characteristics can be used to modify tire manufacture to improve tire uniformity.
