Investigation of tire force transmission on interaction with slush

摘要

The main parameters describing the interaction between a tire and the roadare forces transmitted by a tire. This paper presents experimental and theoretical researchof mechanism of force transmission between a tire and slush-covered pavement. Theexperimental research was conducted in the internal drum test facility at the KarlsruheInstitute of Technology in Germany. The theoretical research presents a mathematicalmodel of the system “"sub-block–slush layer–drum” focusing on slush behavior. Themodel evaluates mass change velocity of slush layer, mass, and physical–mechanicalproperties of sub-block. Slush was analyzed as a multi-layer bulk. The obtained velocitiesof slush layers and friction forces from the model allowed us to determine the generatedheat per time unit at each layer. It was found that the top layer of slush has the highestvelocity and heat flow values compared to other layers.
