Testing the assumption of linear dependence between the rolling friction torque and normal force

Testing the assumption of linear dependence between the rolling friction torque and normal force

Blog Article

Rolling friction is present in all nonconforming bodies in contact.A permanent topic is the characterization of the moment of rolling friction.A number of authors accept the hypothesis of linear dependency Protection between the rolling torque and the normal force while other researchers disagree with this assumption.

The present paper proposes a method for testing the hypothesis of linear relationship between rolling moment and normal pressing force.A doubly supported cycloidal pendulum is used in two situations: symmetrically and asymmetrically supported, respectively.Under the hypothesis of a linear relationship, the motions One Hitters of the pendulum should be identical.
