Description
Technical Field

Background
Rail corrugation is a periodic wave-like irregularity on the top surface of the rail distributed longitudinally. The occurrence of rail corrugation causes the rolling stock and the rail to generate violent vibration, and the damage to the rail is great. The irregularities in the rail surface cause a sharp increase in wheel-rail forces, thereby shortening the service life of the rail and rolling stock related components. In addition, the wave mill can also cause the lower ballast bed and the roadbed to suffer serious damage (such as ballast pulverization, ballast bed hardening, fastener loosening and the like), so that the damage rate of each part of the line is increased, the maintenance workload and cost of a work department are greatly increased, the running resistance of the train is also increased, and if the wave mill is serious, the ballast bed is damaged, and the steel rail and the axle are possibly broken to endanger the driving safety due to the increase of the acting force of the wheel rail. Meanwhile, noise and vibration generated by the corrugation can cause discomfort to passengers, and influence the riding environment and the life of residents along the line.
At present, a plurality of test methods for measuring the rail corrugation wavelength and the corrugation depth exist, wherein the mainstream method for measuring the rail corrugation wavelength and the corrugation depth is two methods of inertial reference measurement and laser measurement. Both methods require preparation of complicated measuring devices, are expensive, have complicated operation procedures, and require multiple users to operate. In addition, the two existing testing methods can only measure the wavy abrasion at the center of the top of the steel rail, and the measurement is inaccurate for the composite type wavy abrasion. In practice, the location at which the corrugation occurs may not be just at the very center of the rail head, and there may be significant differences in the type of corrugation near the inside or outside.
It is therefore desirable to have a simple device that can conveniently and quickly measure the corrugation.
