轨道不平顺的探索与复合不平顺的研究

Exploration of Track Irregularity and Study of Composite Irregularity

分析了轨道不平顺的种类、形成原因及影响。重点对复合不平顺的情况进行研究,包括高低/轨向复合不平顺模拟、幅值影响及波长的影响,对高低/轨向不平顺和轨向/水平逆向位复合不平顺的影响进行了研究。目前,关于复合不平顺的研究较少。若轨道有复合不平顺的现象,轮轨动态作用更加复杂。所以,进行复合不平顺与轮轨动力学关系的研究有重要的现实意义与长远意义。

This paper analyzes the types,causes and effects of track irregularity.This paper focuses on the study of composite irregularity,including the simulation of high/low/track composite irregularity,the influence of amplitude and wavelength,and the influence of high/low/rail direction irregularity and track/horizontal reverse position composite irregularity.At present,there are few researches on composite irregularity.If the track has complex irregularity,the dynamic effect of wheel/rail is more complex.Therefore,it is of great practical and long-term significance to study the relationship between composite irregularity and wheel rail dynamics.
