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： 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 by determining one or more high speed uniformity parameters of the tire are provided. The high speed uniformity parameters can be determined by continuously acquiring uniformity data while ramping the tire to and from high speeds. For instance, measured uniformity data can be continuously collected for the tire as the tire is increased to high rotational speeds and decreased from high rotational speeds. The measured uniformity data can then be analyzed to determine one or more high speed uniformity parameters for the tire. For instance, the measured uniformity data can be corrected for non-high speed uniformity contributions to the uniformity measurements, such as contributions resulting from non-uniformity of a road wheel use to load the tire during uniformity testing, contributions resulting from mass unbalance of the tire, and contributions from low speed uniformity parameters of the tire.

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： Improved and more easily implemented methods for predicting uniformity parameters such as uneven mass distribution, radial run out and high speed radial force variation utilize other measurements such as the tire crown thickness variation. When high speed radial force variation is calculated, low speed radial force variation is also measured. Tire crown thickness variation can be measured in different fashions depending on the particular tire manufacturing process employed. By electronically determining resultant uniformity parameters, tires can be improved by rectification to address the uniformity levels. In addition, tire manufacturing can be improved by altering the resultant location of tire crown thickness variation relative to other aspects of the tire and/or tire manufacturing process.
