Improvement of the Uniformity of a Tire Using Estimation of Transient Effects

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.

主权项

1. A method for improving the uniformity of a tire, the method comprising:
obtaining uniformity measurements of a uniformity parameter for each tire in a set of a plurality of tires; analyzing, with one or more processing devices, the uniformity measurements to identify a transient uniformity effect, the transient uniformity effect changing from tire to tire in the set of tires; and modifying the manufacture of one or more tires based at least in part on the transient uniformity effect.
