    • 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.

    • 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.
    • 提供了通过确定轮胎的一个或多个高速均匀性参数来改善轮胎的均匀性的方法和系统。 高速均匀性参数可以通过连续地获取均匀性数据,同时将轮胎从高速度转移到高速度下来确定。 例如,当轮胎增加到高转速并且从高转速降低时,可以为轮胎连续收集测量的均匀度数据。 然后可以分析所测量的均匀度数据,以确定轮胎的一个或多个高速均匀性参数。 例如,可以校正测量的均匀度数据,以对均匀度测量提供非高速均匀性贡献,例如由均匀性测试期间用于加载轮胎的车轮用途的不均匀性导致的贡献,由于质量不平衡导致的贡献 轮胎,以及轮胎低速均匀性参数的贡献。
