Rolling friction for hard cylinder and sphere on viscoelastic solid.
We calculate the friction force acting on a hard cylinder or spherical ball rolling on a flat surface of a viscoelastic solid. The rolling-friction coefficient depends non-linearly on the normal load and the rolling velocity. For a cylinder rolling on a viscoelastic solid characterized by a single relaxation time Hunter has obtained an exact result for the rolling friction, and our result is in...
متن کاملRolling friction of a hard cylinder on a viscous plane
The resistance against rolling of a rigid cylinder on a flat viscous surface is investigated. We found that the rolling-friction coefficient reveals strongly non-linear dependence on the cylinder’s velocity. For low velocity the rolling-friction coefficient rises with velocity due to increasing deformation rate of the surface. For larger velocity, however, it decreases with velocity according t...
متن کاملRolling friction of a viscous sphere on a hard plane
– A first-principle continuum-mechanics expression for the rolling friction coefficient is obtained for the rolling motion of a viscoelastic sphere on a hard plane. It relates the friction coefficient to the viscous and elastic constants of the sphere material. The relation obtained refers to the case when the deformation of the sphere ξ is small, the velocity of the sphere V is much less than ...

The resistance against rolling of a rigid cylinder on a at viscous surface is investigated. We found that the rolling-friction coeecient reveals strongly non-linear dependence on the cylinder's velocity. For low velocity the rolling-friction coeecient rises with velocity due to increasing deformation rate of the surface. For larger velocity, however, it decreases with velocity according to decr...
متن کاملCylinder Rolling on Another Rolling Cylinder
This problem was suggested by Bradley Klee. For the related case of one cylinder rolling inside another, see [1]. When one cylinder is directly above the other, we define the line of contact of the lower cylinder, 1, with the horizontal plane to be the z-axis, at x = y = 0. Then, the condition of rolling without slipping for the lower cylinder is that when it has rolled (positive) distance x1, ...
