摘要
本文对曲线轨道无缝线路呼吸变形及弹动现象产生的机理进行了初步分析。指出曲线轨道无缝线路在受力方面的最大特点是存在径向温度分力,其变形失稳规律与直线轨道不同;对曲线轨道无缝线路稳定问题的深入研究具有重要的理论和实践意义。
his paper presents an analysis of the behavior of the curve breathing of the continuously welded rails of sharp curved tracks and an analysis of the mechanism of the curve springing buckling. It is pointed out that owing to the radial temperature component.force,the deforming behavior of the curved track is different from the tangent track. This is very important for the further study of the stability of the curved CWR tracks.
