“…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.…”
