铁路小半径曲线外轨侧磨影响因素分析
Analysis of influencing factors on side wear of small radius curve
摘要
Abstract
With the rapid development of railway towards heavy haul and high density, rail wear is becoming more and more serious, which extremely affects the cost and safety of railway operation. Based on the Shijiazhuang-Taiyuan line, this paper mainly studied the influencing factors of the side wear and measures to slow down it on curved railway. Firstly, this paper analyzed the laws of the five main points of the side wear on the small radius curves, indicating that the side wear is more serious on circle curve while the development speed of the side wear is much faster on transition curve. Secondly, by generalized control variable method and statistical analysis means, that how the service life and the slope ratio affected the side wear was analyzed respectively. It was found that the side wear of new rail generally grows linearly after 4~5 months. It also decreases first and then increases with the growth of slope ratio. Finally, the conclusion of the comprehensive article is summarized.关键词
