基于小波的列车加速度和轨道不平顺关系分析

轨道不平顺是引起车辆系统振动的重要激振源．为适应现代铁路的发展，提高旅客乘车的舒适性，研究轨道高低不平顺与列车垂向加速度间的关系变得越来越重要．本文利用小波分析的方法，对综合检测车采集到的轨道高低不平顺信号和垂向加速度信号进行处理，将分析的重点集中在具体的某一频段上，并对其进行了相关性分析，确定了轨道高低不平顺和列车垂向加速度间的关系．

An Analysis of the Relationship of Acceleration and Track Irregularity Based on Wavelet

Track irregularity is an important excitation source which can cause vibration of the Traffic-Track system.In order to adapt to the modern railway development,improve the comfort of passengers,it is increasingly important to research the relationship between track irregularity and vertical acceleration.In this paper,the signals of the longitudinal level and vertical acceleration collected by high-speed track inspection car are processed by using wavelet analysis method.The key points are focused on the spec...
