  • Multi-Objective Optimization of Rail Pre-Grinding Profile ...

    Aug 10, 2018 · In order to modify the rail pre-grinding profile smoothly, non-uniform rational B-spline (NURBS) curve with weight factors is used to establish a parameterized model of the profile. A wheel-rail contact stochastic finite element model (FEM) is constructed by the Latin hypercube sampling method and 3D elasto-plastic FEM, in which the wheelset ...

  • Influencing Mechanism of Rubber Wheel on Contact Pressure ...

    Rail grinding has been widely recognized as an essential measure in routine maintenance of railway network in the world. Compared with other technologies, the emerging abrasive belt grinding process for direct rail maintenance rather than limited polishing finish has shown the convincing potential to improve metal removal rate and surface quality.

  • A new grinding strategy to improve the acoustic properties ...

    Rail grinding is a special application of high-performance dry grinding, which combines a number of special characteristics, such as high feed speed, good surface roughness and waviness and a high material removal rate. Since beginning of the 20th century, rail grinding is used as a maintenance process and is essential for the increased rail life.
