摘要： Systems and methods for improving tire uniformity include identifying at least one candidate process harmonic and corresponding period. A set of uniformity waveforms is then collected for each test tire in a set of one or more test tires. To provide better data for analysis, the collection of waveforms may include multiple waveforms including measurements obtained before and/or after cure, in clockwise and/or counterclockwise rotational directions, and while the tire is loaded and/or unloaded. The uniformity waveforms may be re-indexed to the physical order of the at least one candidate process harmonic, and selected data points within the waveforms may optionally be deleted around a joint effect or other non-sinusoidal effect. The re-indexed, optionally partial, waveforms may then be analyzed to determine magnitude and azimuth estimates for the candidate process harmonics. Aspects of tire manufacture may then be modified in a variety of different ways to account for the estimated process harmonics.

摘要： Methods and systems for improving tire uniformity through identification of characteristics of one or more candidate process effects are provided. The magnitudes of process harmonics associated with one or more candidate process effects can be identified by combining uniformity measurements for a set of tires to achieve an enhanced resolution for a sampling of the process harmonic. The enhanced resolution approach can combine uniformity measurements for a set of a plurality of tires that are slightly offset from one another to generate a composite process harmonic sampling. In particular, the composite process harmonic sampling can be generated by aligning the uniformity measurements for each tire in the set of tires based on the azimuthal location of the maximum magnitude of the process harmonic on each tire. The magnitude of the process harmonic can then be determined using the composite process harmonic sampling.

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： A system and related method for improving tire uniformity includes identifying at least one candidate process effect and a corresponding process harmonic number for each process effect. 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 a test set, such that the measurements contain tire harmonics as well as a process harmonics corresponding to each candidate process effect. Rectangular coordinate coefficients are electronically constructed for each said process harmonic, after which point the rectangular coordinates corresponding to each process harmonic are solved for (e.g., by using regression-based analysis). The magnitude of each said process harmonic is estimated, and a final magnitude estimate for each process harmonic can be determined by summarizing (e.g., by taking the average or median value) the respectively estimated magnitudes for each process harmonic across all test 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： Systems and methods for improving tire uniformity through identification of transient effects contributing to the non-uniformity of a tire are provided. More particularly, uniformity measurements can be obtained for a set of a plurality of tires. The uniformity measurements can include contributions from tire harmonic uniformity effects (e.g. effects attributable to tooling elements used during tire manufacture) as well as process harmonic uniformity effects (e.g. effects attributable to process elements used during tire manufacture). Certain of the tire harmonic uniformity effects can be transient effects that change from tire to tire. For instance, the effect attributable to a curing membrane used during the curing process can transiently change from tire to tire. Aspects of the present disclosure are directed to identifying transient effect contributions to uniformity measurements and improving the uniformity of the tire using the identified transient effect contributions.

摘要： Methods and systems for improving the uniformity of a tire 200 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.
