研究論文 回転するラジアルタイヤサイドウォールのばね定数評価

抄録

The spring bedded ring model has been widely used for structural analyses of tire deformations under quasi-static and dynamic loading. Analyses on spring constants in the radial, the lateral and the circumferential directions, denoted by K_r, K_s and K_t respectively, have been conducted previously, however, were confined to only static cases. In this paper, by solving the equilibrated configuration of radial tire sidewall under inflation perssure and centrifugal force, we obtain finite deformations due to various loadings at the sidwall end near the tread. Then, we determined non-linear spring constants of a rotating radial tire K_r, K_s and K_t, which are compared with the experimental results given by referred papers.
