Abstract A three-component model for a belted radial tire, previously developed by the authors for free rolling without slip, is generalized to include longitudinal forces and deformations associated with driving and braking. Surface tractions at the tire-road interface are governed by a Coulomb friction law in which the coefficient of friction is assumed to be constant. After a brief review of the model, the mechanism of interfacial shear force generation is delineated and explored under traction with perfect adhesion. Addition of the friction law then leads to the inception of slide zones, which propagate through the footprint with increasing severity of maneuvers. Different behavior patterns under driving and braking are emphasized, with comparisons being given of sliding displacements, sliding velocities, and frictional work at the tire-road interface. As a further application of the model, the effect of friction coefficient and of test variables such as load, deflection, and inflation pressure on braking stiffness are computed and compared to analogous predictions on the braking spring rate.

Das Programm Sugars™ für Windows® erstellt komplett die Massen-, Energie- und Farbbilanzen für Rüben- und Rohrzuckerfabriken sowie Raffinerien. Das Programm simuliert nahezu jeden Prozess der Zuckergewinnung. In diesem Beitrag wird die Simulation einer Rübenzuckerfabrik mit Melasseentzuckerung mittels chromatographischer Trennung vorgestellt. Das vollständig integrierte Modell beinhaltet die in die Schneidemaschinen gelangenden Schnitzel bis hin zur chromatographischen Abtrennung der Saccharose aus Melasse und der Einengung von Extrakt, Betain und Raffinat. Außerdem enthält es Angaben zur Dampf- und Stromerzeugung. Sugars stellt Schnittstellen für den Datenimport und -export bereit. Ein Beispiel zeigt den Export der Turbogeneratordaten des Modells nach Microsoft Excel®. Hierbei wird der isentrope Wirkungsgrad unter Verwendung der Willans-Linie modifiziert, um die Leistungsfähigkeit des Turbogenerators zu verändern. Der so berechnete isentrope Wirkungsgrad wird zur Neubilanzierung des Modells von Excel wieder nach Sugars exportiert.
