The problem of a hard cylinder rolling with constant velocity over a viscoelastic half space has been treated in terms of the bulk properties of the half space. It was theoretically found that the rolling friction changes with the relaxation time T; when T is very small, the frictional moment is proportional to the velocity of the cylinder, whereas, when T is very large, the moment is independent of the velocity. The attenuation of the amplitude of a swinging pendulum consists of two terms, one is in proportion to the velocity and the other is a constant. When the amplitude becomes very small, the constant term of the moment diminishes.

Abstract


The problem of a hard cylinder rolling with constant velocity over a viscoelastic half space has been treated in terms of the bulk properties of the half space. It was theoretically found that the rolling friction changes with the relaxation time T; when T is very small, the frictional moment is proportional to the velocity of the cylinder, whereas, when T is very large, the moment is independent of the velocity. The attenuation of the amplitude of a swinging pendulum consists of two terms, one is in proportion to the velocity and the other is a constant. When the amplitude becomes very small, the constant term of the moment diminishes.
