Tire friction coefficient
WebThe load sensitivity of most real tires in their typical operating range is such that the coefficient of friction decreases as the vertical load, Fz, increases. The maximum lateral force that can be developed does increase as the vertical load increases, but at a diminishing rate. Behaviour [ edit] WebWhen tires experience slip, they develop a longitudinal force, Fx. The contact patch slip velocity is V s x = V x − r w Ω − u ˙. For a tire without compliance, u = 0. The unsmoothed contact patch slip is k = − V s x V x , and the block saturates the slip denominator as V x = { V X L O W if V x < V X L O W V x otherwise
