Tire Viscoelasticity Characterization for Adhesion Phenomena Analysis by Using the VESevo Innovative Technology

In vehicle dynamics, the study of the viscoelastic characterization of tires is crucial for a better understanding of the adhesion phenomenon during tire-road interaction, with the ultimate goal of enhancing vehicle performance and safety. The viscoelastic characterization of polymeric specimens traditionally involves costly and destructive practices. However, the development of the VESevo device has allowed to overcome these limitations for tire viscoelasticity characterization. This paper presents an analysis on tire adhesion by considering three different compounds tested with the VESevo device, to compare the acquired curves with and without the use of talc on the compound. Additionally, since the adhesion phenomenon is dependent on temperature, the various specimens were heated to explore the thermal effect. The paper investigates the adhesion variances among soft, medium, and hard compounds under changing temperature and compound conditions, commencing with rebound curve comparisons with and without talc.
