“…where is the mass of sub-block, are the stiffness and damping coefficients, respectively, and is the angle between radius and centrifugal force direction, calculated as follows: (10) The friction force between slush and tire was evaluated using the friction model presented in [19]. Then, friction force can be expressed as , (11) where is the difference between the slush velocities, are force coefficients, and is the normal force of wheel load.…”

The main parameters describing the interaction between a tire and the road are forces transmitted by a tire. This paper presents experimental and theoretical research of mechanism of force transmission between a tire and slush-covered pavement. The experimental research was conducted in the internal drum test facility at the Karlsruhe Institute of Technology in Germany. The theoretical research presents a mathematical model of the system ""sub-block-slush layer-drum" focusing on slush behavior. The model evaluates mass change velocity of slush layer, mass, and physical-mechanical properties of sub-block. Slush was analyzed as a multi-layer bulk. The obtained velocities of slush layers and friction forces from the model allowed us to determine the generated heat per time unit at each layer. It was found that the top layer of slush has the highest velocity and heat flow values compared to other layers.

“…There are studies on the mechanism of force transmission of tire in snow or ice [9][10][11][12] and the friction mechanism between tire tread blocks and ice or snow-covered pavement [13][14][15], but there is a lack of studies analyzing the interaction between a tire and slush. The closest investigation is presented by Lee and Huang [16].…”
