Understanding Test Modalities of Tire Grip and Laboratory-Road Correlations with Modeling

Abstract The present study is meant to obtain tribological insight into the interface of a rolling rubber wheel on counter-surface disk based work previous Salehi et al. (Tribol Lett 68(1):37, 2020), in which new test method was developed rapidly predict tire grip laboratory environment. A Laboratory Abrasion Tester (LAT100) used and exploited as tribometer. This opened cost- time-effective horizon for material development environment rather than having tread compounds by building full-scale tires. validated comprehensive six different compositions, correlating data solid wheels LAT100 specimens with real results two modalities: lateral ( ? ) longitudinal ? sweep tests dry road. It demonstrated that can be simulate $$\alpha$$ ? -sweep tests, but not $$\kappa$$ ? -sweep. dynamics physics step-up are investigated utilizing renowned physical “brush model” comparison tests. type modality leads friction mechanisms contact patch even at similar conditions. substantiated recognizing regions: stationary non-stationary, area components mechanisms. behavior movements same conditions comparable if contributions mentioned regions similar.
