摘要
轨道竖向刚度不均匀是道岔的主要缺陷之一。文章通过应用有限元方法对道岔区轨道竖向刚度不均匀进行分析,探讨道岔区轨道竖向刚度不均匀对列车运行舒适性和安全运营的影响,研究控制平顺的必要性,进一步探讨提出相应的在线检测方法。
The uneven of vertical stiffness in track is one of the major flaws of railroad switch.This paper,through the analysis of finite element method on inhomogeneous vertical stiffness of railroad switch,explores that the uneven of vertical stiffness in track have impact on the comfort and safety of operation,the necessity of regulating smoothly,and then proposes the homologous method of on-line detection.
