【摘要】 轨道动态几何不平顺数据主要采用轨检车进行检测,由于缺乏去除功能,轨检车检测数据中存在噪音成分,不利于轨道质量状态的客观评价.本文提出去除噪音的方法,并利用概率密度法,对高低不平顺幅值特征进行统计描述,比较去除噪音前后的效果.更多还原

【Abstract】 Due to lacking the function to eliminate the noise, in the data of railway track irregularities which are obtained by track inspection car, the evaluation of track quality will be influenced. In this paper, a method is proposed to locate and remove the noise and probability- density-method is given to describe the characters of vertical profile irregularity breadth and compare the effect before removing the noise with after removing it.更多还原
