Abstract
Devises using the rolling of viscoelastic materials such as rubber is proposed, and a practical procedure for easy evaluation of the rolling resistance of them is required. This kind of research has been already established in the field of tire technology, and many patents are submitted. One of the approaches to simulate the rolling resistance of viscoelastic materials is to calculate the energy dissipation of a rolling model from the strain and stress obtained from a finite element-based method of an elastic model, and the loss factors of the material determined separately. In this paper, a new devise using the rolling of O-ring rubber is proposed and the method of simulating the rolling resistance of viscoelastic materials is applied. Compared with an experiment and dynamic finite element analysis, the validity and the qualitative aspects of the proposed method are discussed.
