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 harmonic magnitudes associated with a plurality of harmonics of the composite uniformity parameter. For instance, a 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 harmonic magnitudes 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 Weibull distributions of the harmonic magnitudes. Once identified, the one or more characteristics can be used to modify tire manufacture to improve tire uniformity.

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 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： 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： A tire manufacturing method includes a method for optimizing the uniformity of a tire by reducing the after cure radial force variation. The after cure radial force variation vector is modeled as a vector sum of each of the vectors representing contributions arising from the tire building steps - the "tire room effect vector" and a vector representing contributions arising from the vulcanization and uniformity measurement steps - the "curing room effect vector." In further detail, both the tire room and curing room effect vectors can be further decomposed into sub-vectors representing each radial force variation contribution for which a measurable indicator is available. For a series of tires, the method obtains such measurements as the before cure radial runout (RRO) at one or more stages of the building sequence, measurements of loading angles on the tire building equipment, and measurements made during vulcanization process.

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： 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 known 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 m th harmonic 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 or offset in some fashion by location of other tire contributions.

摘要： A system and related method for improving tire uniformity includes providing at least one set of test tires constructed with one or more process elements provided at known relative angular locations. At least one uniformity parameter, such as radial or lateral run-out, balance, mass variation, radial lateral or tangential force variation, is measured for at least one harmonic of interest for each test tire. Respective rectangular coordinates are determined for each measured uniformity parameter and harmonic of interest for each tire. A form of the determined rectangular coordinates (e.g., the rectangular coordinates themselves and/or the log of the residuals squared) is analyzed for each tire to identify optimized relative angular locations for each process element that reduce dispersion (or dispersion and mean) of the measured uniformity parameter. New tires are built with the one or more process elements positioned in the identified optimized relative angular locations.
