Abstract

Vehicle dynamics is largely influenced by the phenomena occurring in the tire-road interface, and a great portion of these phenomena is mainly conditioned by the viscoelastic properties of the tire tread compound. It is not surprising that the possibility of obtaining the viscoelastic response of a compound by means of a nondestructive procedure is a growing research topic that affects application fields ranging from monitoring of the material performance during its entire life cycle to the quantitative analysis of product quality and repeatability of production processes. In this article, a novel nondestructive procedure for the viscoelastic characterization of tire tread compound is proposed. A portable instrument, based on instrumented indentation, was designed and prototyped with the aim to allow a real-time assessment of moduli directly on site. The testing procedure adopted to perform the test on three different compounds was described. A signal-processing procedure was developed for the identification of compound stiffness and damping parameters from which viscoelastic moduli were estimated. The results were also compared with the DMA characterization showing the same relative ranking between the compounds with a different trend in temperature due to the amount of the tests' indentation depth.

一种新的轮胎胎面粘弹性无损检测方法

车辆动力学在很大程度上受到轮胎-道路界面中发生的现象的影响，而这些现象中的很大一部分主要受轮胎胎面胶的粘弹性性质的制约。毫不奇怪，通过无损程序获得化合物粘弹性响应的可能性是一个日益增长的研究课题，它影响着从材料整个生命周期的性能监测到产品质量和生产过程可重复性的定量分析等应用领域。本文提出了一种新的无损检测方法来表征轮胎胎面胶的粘弹性。设计并原型化了一种基于仪器压痕的便携式仪器，旨在直接在现场实时评估模量。描述了对三种不同化合物进行试验所采用的试验程序。开发了一种信号处理程序，用于识别复合刚度和阻尼参数，从而估计粘弹性模量。结果还与DMA表征进行了比较，DMA表征显示由于测试的压痕深度的量，具有不同温度趋势的化合物之间具有相同的相对等级。
