The Profile Curve of Tooth-Shaped Roller Influence on the Rolling Force of Corrugated Web Rail

Abstract:

The corrugated web rail is a special kind of rail structure. Horizontal roller of rolling the corrugated web rail is named as tooth-shaped roller because its shape is close to straight tooth gear. The profile curve of tooth-shaped roller has great influence on the finish product quality , the rolling process and the rolling force of the corrugated web. In this paper, profile curve of tooth-shaped roller of rolling corrugated web rail was designed. FEM model of rolling corrugated web rail was established and the rolling process was simulated by the software ANSYS/LS-DYNA. In the condition of the same reduction and the same rolling speed, the rolling force was compared of experiment profile curve with the designed profile curve. According to the analysis results, the rolling force of the designed profile curve is significantly smaller than that of experimental profile curve. Therefore, it is necessary to optimize profile curve of the tooth-shaped roller to decrease the rolling force.
