HystérésisL'hystérésis (ou hystérèse) et signifiant "après" ou "plus tard", est la propriété d'un système qui tend à demeurer dans un certain état quand la cause extérieure qui a produit le changement d'état a cessé.

| Résumé : |
Recently, the research on low rolling resistance tires attracted interest for its reduction of petrol consumption, which is related to the hysteresis loss of rubber composites. Here, four common methods representing the hysteresis loss of rubber composites in lab were contrasted to explore the potential connections between them. The results indicated that tan δ obtained by DMA showed good positive linearity with that obtained by RPA without distinguishing the rubber species and filler types, also for the positive relation between tan δ and hysteresis loop area (HLA). The rolling power loss (L) captured by the rolling resistance testing machine appeared to have a positive correlation with tan δ from DMA or RPA in NR composites, while a negative connection showed up in SBR composites. Further, considering the influence of strain on rolling energy loss, the 100% modulus was introduced leading to a good positive quadratic equation connection between tan δ/100% modulus and L in all common rubber composites. |
