Abstract

ABSTRACT Uniformity characteristics of a tire are a direct reflection of the quality of the manufacturing process that produced it. This is realized in the homogeneity of its different stiffnesses and dimensions around the tire. Evidently, this is the most closely monitored aspect for consistency, from the original equipment manufacturers and manufacturers alike, and the requirement for tighter acceptance criteria is ever-increasing. However, the authors endeavor to find the lowest theoretical level for the same, given the intrinsic sources. The current study attempts to establish a framework to investigate the effect of the most pronounced factors individually, their interplay, and how their combined effect can be minimized. The present work on a 185/65R15 passenger car radial tire attempts to determine the effect of variable pitch sequencing as well as splicing and tread runout for a patterned tire on radial force variation (RFV). The study is carried out using finite element simulation for it presents the opportunity to study the individual effects systemically and economically. The study reveals a nearly 20% of the specification limit can be due to tread pattern sequence while the effect of the overlapping components may vary by 10% of the same limit. The study also suggests spotting arrangements to target and avoid. Finally, the authors present a method, captured in a MATLAB program that benefits the tire designer, plant engineer, and quality control manager.

非均匀性的内在源及其相互作用的建模

轮胎的均匀性是制造过程质量的直接反映。这是通过其在轮胎周围不同刚度和尺寸的均匀性来实现的。显然，这是最密切监控的一致性方面，从原始设备制造商和制造商一样，要求更严格的验收标准是不断增加的。然而，考虑到内在的来源，作者努力寻找最低的理论水平。目前的研究试图建立一个框架来调查最显著的因素的影响，他们的相互作用，以及如何将他们的综合影响最小化。本研究以185/65R15轿车子午线轮胎为研究对象，试图确定变间距排序、拼接和花纹轮胎胎面跳动对子午线力变化(RFV)的影响。本研究采用有限元模拟进行，因为它提供了系统和经济地研究个体效应的机会。研究表明，胎面花纹序列对轮胎性能的影响约为20%，而重叠部件对轮胎性能的影响仅为10%。该研究还建议确定目标和避开的安排。最后，作者提出了一种方法，用MATLAB程序捕获，使轮胎设计师、工厂工程师和质量控制经理受益。

期刊介绍： Tire Science and Technology is the world"s leading technical journal dedicated to tires. The Editor publishes original contributions that address the development and application of experimental, analytical, or computational science in which the tire figures prominently. Review papers may also be published. The journal aims to assure its readers authoritative, critically reviewed articles and the authors accessibility of their work in the permanent literature. The journal is published quarterly by the Tire Society, Inc., an Ohio not-for-profit corporation whose objective is to increase and disseminate knowledge of the science and technology of tires.
