Abstract
The design of a vehicle, whatever it is, is strongly influenced by the characteristics of the tire: it is important to understand how this determines the driveability, safety, performance, efficiency and comfort of the vehicle. The tire supports the weight of the vehicle and allows the forces of interaction with the road to be exchanged. It is one of the main examples of viscoelastic material for which the evaluation of the viscoelasticity of tires is a fundamental issue that aims at the development of polymers for innovative compounds, for the optimization of vehicle performance and road safety. The viscoelastic properties of tires are commonly determined by destructive methods among which dynamic mechanical analysis (DMA) is the most widespread. However, this method has several disadvantages, including the need to produce samples to be tested in the laboratory. In the automotive sector, on the other hand, the need to safeguard the entire structure is often dictated by regulations: it is therefore important to study alternative methods of analysis. In this work, a specific innovative and non-destructive device is presented to determine the dynamic characteristics of the compound of a tire. Specifically, the activity is aimed at developing experimental tests, carried out with the device, on different tire compounds to determine their viscoelasticity. The need to develop prototypes, which allow non-destructive analysis of the material, thus benefiting the analysis of a tire from a temporal point of view and from an economic point of view, is spreading in the world panorama of the development of racing and road tires.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
