| Research Abstract |
We proposed a noncontact concurrent monitoring method for measurements of tire in-plane strain and out-of-plane displacement(rolling radius) by embedding a CCD camera on wheel rim. By combining digital image correlation method and spotlight projection, in-plane and out-of-plan displacement can be obtained from one image taken by a single camera. The proposed system was applied to automobile radial tires and it was proved to be able to measure rolling radius and in-plane strain distribution with high accuracy.
