Patent number: 10279636Abstract: Systems and methods for improving the uniformity of a tire by identifying the effects of tooling elements used during tire manufacture on tire uniformity, such as effects resulting from building drum elements, form elements, mold elements, and other tooling elements, are provided. More particularly, a tooling signature of a tooling element can be identified by analyzing a plurality of uniformity waveforms measured for a set of tires manufactured using the tooling element. The tooling signature can be analyzed and used to modify tire manufacture to improve the uniformity of a tire.Type: GrantFiled: September 28, 2012Date of Patent: May 7, 2019Assignee: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventors: William David Mawby, Jonathan Sauls, James Michael Traylor

Patent number: 10024763Abstract: 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.Type: GrantFiled: December 14, 2012Date of Patent: July 17, 2018Assignee: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventors: Verner Steve Nicholson, James Michael Traylor

Patent number: 9823153Abstract: 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.Type: GrantFiled: June 18, 2013Date of Patent: November 21, 2017Assignee: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventors: William David Mawby, Steve Simons, James Michael Traylor, Anton Felipe Thomas, Jonathan Sauls

Patent number: 9778032Abstract: 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.Type: GrantFiled: December 2, 2010Date of Patent: October 3, 2017Assignee: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventors: Julien Matthieu Flament, Verner Steve Nicholson, Anton Felipe Thomas, James Michael Traylor

Patent number: 9645052Abstract: 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.Type: GrantFiled: September 16, 2011Date of Patent: May 9, 2017Assignees: MICHELIN RECHERCHE et TECHNIQUE S.A., COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventors: William David Mawby, Jimmy Jeter, Jonathan Sauls, James Michael Traylor

Publication number: 20160236431Abstract: 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.Type: ApplicationFiled: November 8, 2013Publication date: August 18, 2016Inventors: William David MAWBY, James Michael TRAYLOR, Casey APPLEMAN

Publication number: 20160003711Abstract: Systems and methods for estimating a uniformity parameter 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 and lateral force variation measurements. Deconvolution can be used to estimate radial run out from one or more uniformity parameter measurements, including radial force variation parameter measurements and lateral force variation measurements. The estimated uniformity parameter can be estimated from the measured radial uniformity parameter 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.Type: ApplicationFiled: March 29, 2013Publication date: January 7, 2016Inventors: William David MAWBY, James Michael TRAYLOR

Publication number: 20120267031Abstract: A tire manufacturing method includes a method for optimizing the uniformity of a tire by reducing the green tire radial runout. The green tire radial runout is modeled as a vector sum of each of the vectors representing contributions arising from the tire building steps. A set of vector coefficients is generated from the vector equation. The building steps include building the tire carcass, building the tire summit, transferring the summit onto the inflate carcass, and measuring the radial runout and tooling angles at each step in the process. After the model is built, the vector equations and coefficients are applied to subsequent tires. By adjusting the tooling angles, green tire radial runout can be optimized.Type: ApplicationFiled: June 19, 2012Publication date: October 25, 2012Inventors: William David Mawby, James Michael Traylor, Eugene Marshall Persyn

Patent number: 8287675Abstract: 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.Type: GrantFiled: January 26, 2011Date of Patent: October 16, 2012Assignee: Michelin Recherche et Technique S.A.Inventors: William David Mawby, George Phillips O'Brien, Eugene Marshall Persyn, James Michael Traylor
