Influence of Wheel Profiles Evolution on Wear of Fixed Frog in Heavy Haul Railway

doi:10.3901/JME.2020.10.208

Abstract

Abstract: For Datong-qinhuangdao Line, in order to study the influence of the evolution of the wheel profile on the fixed frog, the dynamic model of heavy haul train and the fixed frog is established to analyze the dynamic performance and wear law of the frog. The results show that after passing the theoretical tip, the radius of the wheel rolling circle changes, causing the linear velocity of the contact point of wheel and frog to change. Besides, for the coexistence of rolling and sliding friction between wheels and frogs, the wing rail wears more seriously. When wheels impact the nose rail, the contact position is relatively concentrated, causing a badly damaged zone on the nose rail. The evolution of the wheel profile changes the contact state between wheels and frogs. Comparing with the standard wheel, the dynamic performance of the worn wheel at the initial stage is better. The ride comfort becomes better and the vertical force becomes lower so that the frog worn slightly. The vertical force of the locomotive wheel and the freight car wheel reduced by 39% and 56% respectively. However, with the evolution of the wheel profile, the wear volume increases and the dynamic performance of the wheel becomes worse. At the later stage of wear, the contact friction between the worn wheel and the frog would cause the severe wear and spalling.

Key words: heavy haul train, fixed frog, wheel wear, dynamic performance, frog damage
