Background
Rail corrugation is a major type of rail damage, which is the periodic wave-like irregularity along the longitudinal surface of the rail, with both wave length and peak-to-valley attributes.
Hazards caused by corrugation are:
1. increase the maintenance cost: when the wheels pass through the corrugation zone, the action force of the wheels and the rails is increased rapidly due to the irregularity of the surfaces of the steel rails, so that the rolling stock and the rails generate severe vibration, and the generation and development of the damage of the rails and the related parts of the rolling stock are promoted, thereby increasing the maintenance cost; and the rail is violently vibrated when the train passes through the corrugation zone, so that the pulverization rate of the ballast is accelerated, the slurry and mud are blown out of the track bed, the rail fastener is loosened, the threaded spike, the gauge rod is broken in a large quantity, the sleeper is hung in an empty state, the rubber mat is damaged, and the maintenance cost is greatly increased.
2. Noise pollution: when the train passes through the corrugation zone, great noise is generated, and great harm is brought to residents along the railway; at the same time, this noise can also affect the passengers, causing them to feel uncomfortable.
3. Potential safety hazard: if the wave abrasion of the steel rail is serious, the impact force is increased sharply when the train passes through the wave crest, and the stress is reduced when the train passes through the wave trough, so that the load shedding and the derailment of the train are easily caused, the fracture of the steel rail and an axle is also easily caused, and the driving safety is influenced.
4. Increase energy consumption: due to the irregularity of the corrugation rail surface, poor adhesion of the wheel rail is caused, and accordingly, the running resistance of the wheel rail is increased. In addition, the vibration of the wheel-track system is intensified, so that the damage rate of components is increased, and a large amount of energy is consumed, and the energy must be provided by the traction force of the locomotive, so that the energy consumption is increased.
At present, the domestic corrugation detection of the steel rail basically adopts foreign corrugation detection equipment. CAT corrugation test equipment manufactured by Railmeasurement, Inc. of UK is more common. The operator finds, when using a CAT corrugation test device: 1) The scale marking the position of the probe of CAT corrugation detection equipment is in a corner form, namely only the number of corners can be provided, so that when an operator adjusts the position of the probe, the specific position size is not clear, the positioning precision is not enough, the expression of a measurement structure is not clear, finally, only guidance suggestions can be provided for the grinding of the surface of the steel rail, and grinding points cannot be accurately positioned; 2) the scale of CAT ripples grinds check out test set is located the equipment bottom, in the use, just places the rail after the adjustment on, because the train automobile body shelters from can't confirm that whether the probe for detection adjusts in place, needs many times repeated adjustment operation, just can aim at the measured line position, has increaseed the complexity of detection achievement, has seriously influenced work efficiency.
