타이어 플랫스팟 현상 분석과 평가 모드 개발

When vehicle is stayed at one spot or carried by transport for a long time, tire is deformed by environment elements. It is called tire flat spotting phenomenon. This tire deformation makes the vibration of the vehicle like steering wheel shake, body's under-floor tremble. This research analyzed the results which are induced by each environment elements and found the root causes of the tire flat spotting. It showed that the root causes are the carcass weakness and the stress concentration locally of tire tread applied to the tires. Finally this research suggests the re-occurrence test process for prevent of the tire flat spotting before tire mass production.
