    • 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.
    • 轮胎制造方法包括通过减小固化后的径向力变化来优化轮胎的均匀性的方法。 后固化径向力变化矢量被建模为表示轮胎建造步骤产生的贡献的每个矢量的矢量和 - 轮胎室效应矢量和表示由硫化和均匀性测量步骤产生的贡献的矢量 - 固化室效应 向量。 更详细地,轮胎室和固化室效应矢量可以进一步分解成表示可测量的指示符可用的每个径向力变化贡献的子向量。 对于一系列轮胎,该方法在建筑物顺序的一个或多个阶段获得诸如前固化径向跳动(RRO)的测量,轮胎建筑设备上的负载角度的测量以及硫化过程中的测量。

    • 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.
