摘要
轨道不平顺的检测通常可分为静态检测与动态检测2种类型。根据现场经验,动静态检测值之间往往存在一定的偏差。针对轨道不平顺中的高低不平顺,提出一种分析其动静态关系的方法,该方法首先建立一个动静态关系的计算模型,然后通过编程将其实现,最后结合现场实验数据对方法的适用性进行分析。分析表明,该方法能够在一定程度上较好地由动态不平顺原波形推算静态不平顺的原波形,但当实际静态不平顺波形在波峰处偶尔超过或明显低于动态不平顺波形时,则有可能无法被准确还原;因此具有一定的局限性。
There are two types of track irregularity detection, namely static detection and dynamic detection. According to the field experience, there are some differences between the dynamic and static detection values. This paper proposes a method to analyze the static and dynamic relationship of vertical profile irregularity in track ir- regularity, which firstly establishes a calculation model of the static and dynamic relationship, then realizes it by programming, and finally analyzes the applicability of the proposed method based on the field experimental data. The analysis shows that this method could accurately calculate the corresponding static irregularity to a certain extent, but when the actual waveform of static irregularity is occasionally more than or significantly less than the waveform of dynamic tions. arity at wave crest, the results might be inaccurate, which presents certain limita-
