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.
In order to adapt to the development of modern railways and improve the comfort of passengers, it is more and more important to study the relationship between track irregularities and train vertical accelerations. Using the method of wavelet analysis, the signal of high and low orbit and vertical acceleration collected by the integrated test car are processed, the analysis focuses on a specific frequency band, and the correlation analysis is conducted to determine the The relationship between track irregularities and train vertical accelerations.
