Rail Corrugation of High-Speed Railway Induced by Rail Grinding

چکیده
Rail corrugation is a common railway defect that involves diverse and complex factors. grinding also the most commonly used method to address corrugations. Through numerous irregularity tests one-third octave frequency spectrum analyses, this study determined characteristics development process for rail on high-speed tracks. The vibration transmission properties of train were tested using force hammer impacting method. Thereafter, simulation, influence vertical behavior stone stiffness hydraulics determined. series field numerical simulations, revealed clear correlation between confirmed technical operation closely associated with regular marks at wavelength approximately 60 mm surfaces. combination natural (frequency Hz) an inappropriate operational can aggravate surfaces, thereby forming initial excitation corrugation. Although large number are performed after grinding, these wavelength-fixing cause formation Suggestions improving rail-grinding technology provided.

Rail corrugation detection by Gabor filtering
Inspection of the rail state in order to detect defects is one of the basic tasks in railway maintenance. Rail defects exhibit different properties and are divided in various categories relating to the type and position of flaws on the rail. In this paper, we propose a technique, based on texture analysis of rail surface, to detect and classify a particular class of defects: corrugation.
متن کاملImpacts of Wheel–rail at Railway Turnouts
Investigation of vertical vibrations of a railway turnout is important in designing track components under moving loads of trains. In this paper, the turnout is simulated by a linear finite element model with modal damping. A section of the turnout has a length of 36 sleeper spans surrounding the crossing. Rails and sleepers are modeled with uniform Rayleigh-
Timoshenko beam elements. The ra...
