항공기용 타이어의 마모 수명 예측

다국어 초록 (Multilingual Abstract)

The aircraft tires usually have severe operating constrains requiring high speed, high loads, high inflation pressure and so on. These conditions are causes of very high tire wear rate. So, we need to develop technologies which are related with the estimation of tread wear life for improving aircraft tire. This paper proposes the estimation method of tread wear life through the wear equations, frictional energy rate, and assumption of operational impact rate on wear. The frictional equations for tread wear of aircraft tire are obtained by Lab. wear test. The frictional energy rates with respect to velocities of aircraft tires are calculated by finite element analysis. These results and operational impact rate on wear are used to estimation of tread wear life of aircraft tire.
