摘要: |
A prototype instrument capable of detecting/evaluating ply cord fatigue damage, i.e., the zipper mode of failure, in radial steel-belted truck tires has been developed. The instrument is production-oriented and capable of being used for on-line inspection of new or retreaded tires. Furthermore, the instrument is also capable of providing color-coded scans, thereby reducing the possibility of operator error which could result in damaged tires being placed in service. |
