Fractal Description of Rail Corrugation and Its Dynamic Simulation

  • Received Date: 04 Sep 2008

  • To probe into the method to accurately describe the attrition grade of rail corrugation using fractal dimension,the characteristics of rail corrugation,measured in some segments with a curve radius of 300 m along the Shijiazhuang-Taiyuan railway line,were described by fractal dimension based on experimental data,and its fractal dimension was calculated out.The trace curve of rail corrugation was inputted as track cross-level irregularity,and the vertical displacement,acceleration and other dynamic responses of components under different train speeds were calculated numerically,and the relationship between the dynamic responses and the fractal dimension was investigated.The research shows that the attrition grade of rail corrugation can be described by its fractal dimension and the dynamic responses calculated out and the fractal dimension are influenced by measuring distance
