이종소재 타이어차륜의 기본설계

초록

Current the railway wheels are designed by a monoblock type, but recently in order to reduce weight and noise, a lot of research on the tired wheel is underway. The purpose of this study is to evaluate static and fatigue strength of the hybrid tyred wheel, which has an aluminum alloy wheel center, and to suggest the fundamental design of hybrid wheel which has an equivalent strength with steel forged the monoblock wheel. For the evaluation of the strength of the wheel according to the EN 13979 standard static and fatigue strength analysis has performed, resulting in approximately 30% lighter in the hybrid wheel design proposal can be derived.
