Using cross-sectional shape of the rail-shaped bending section has the best performance, 43kg heavy rail, rail head, composed 43G, crane rail prices, 50G, Hefei heavy rail, 60G-sectional view of the rail web rail and bottom rail of three parts. To enable the rail to better support forces from all aspects, to ensure the necessary strength condition, 38kg heavy rail, rail should be sufficient height, the head and the bottom should be of sufficient size and height, waist and bottom should not be too thin. Corrugation mainly in heavy transport lines, especially coal mine online operation particularly severe in high-speed passenger lines have different degrees occurred on the city subway is also more common. A high speed train railway, mainly corrugated abrasion, and mainly in the lines and the braking area. In the lower speed of heavy transport line the main hair waves abrasion, and generally occurs at the curve section. Multiple factors influence the development of rail corrugation many materials related to the rail line and machine vehicle conditions.
