rolling resistance force


rolling resistance force
the negative longitudinal force resulting from energy losses due to deformations of a rolling tire. Note: this force can be computed from the forces and moments acting on the tire by the road. fr = (mycosy + mzsiny)/rl. Note: this rolling resistance force definition has been generalized so that it applies to wheels which are driven or braked. The wheel torque can be expressed in terms of the longitudinal force, rolling resistance force, and loaded radius by the equation t = (fx + fr)re for a free-rolling wheel, the rolling resistance force is therefore the negative of the longitudinal force
