Pre-grinding Effect of High-speed Railway and Track Irregularity Analysis
摘要
Abstract
High track regularity of high speed railway requires pre-grinding the track before its operation.Adopt-ing Huning High-speed Railway as a sample, by analyzing the state before rail grinding, the paper finds that light brand does not stay in the middle of railhead and two-point contacting problem. Referring to European standard of roughness levels of measuring noise emitted by rail bound vehicles and the standard of rail grinding and milling work in track, the author evaluates the state of longitudinal irregularity by using one-third octave and statistic analysis of amplitude of different wavelength range. Results show that track grinding is an effective measure to correct the surface irregularities greatly.关键词
