Web20 de out. de 2011 · Experimental results have shown that the longitudinal tire force at small “slip ratio” is proportional to the slip ratio. Slip ratio The difference between the actual longitudinal velocity at the axle of the wheel V x and the equivalent rotational velocity r eff ω w of the tire is called longitudinal slip. WebBased on the corrected tire model, and assuming that the vertical load F z is 4 kN, the road friction coefficient is 1.0; the relationships of the longitudinal force and the slip ratio …

WebIn (automotive) vehicle dynamics, slip is the relative motion between a tire and the road surface it is moving on. This slip can be generated either by the tire 's rotational speed … Web7 de ago. de 2015 · In the premise of constant normal pressure, when the wheel slip ratio is small, longitudinal force linearly increases with slip ratio. With further increase of the slip ratio, longitudinal force increases and then decreases nonlinearly. When the longitudinal force reaches a maximum value, the corresponding slip ratio is called optimal slip ratio.
