Abstract. First aim of this paper is to outline the rolling friction between tire and the road surface and then introduce the friction as a force transmitter. In continue, we mount the friction force between the tire and the pavement and then simulate the friction. Installing a shaker at top of the brake system, could add vertical force to the weight of the mass, that influence the friction force. changing the frequency of the shaker, could influence the friction force a lot. Braking and proportion systems could be more efficient by using this Innovation.
