| Research Abstract |
To investigate the dynamics in the contact interface appearing at the stick-slip transition in sliding systems, we invented a belt-cylinder-type experimental apparatus employing a high-speed video that enables us to observe contact area at a rate of 1,000,000 frames per second. Temporal changes of the real contact area and the internal stress of the belt were obtained from the optical images and the photoelastic images, respectively. We established a method to identify when and where vibration and noise are generated, which is induced by the stick-slip transition.
