Study on the geometry dimension effect of heavy rail through compound roll straightening
The paper starts with the active straightening regulations of the compound-roller straightener in certain factory. It adopted the explicit dynamics FEM software ANSYS/LS-DYNA and carried out the numerical simulation calculation of the compound-roller straightening process for 60 kg/m heavy rail with original curvature. It also made post-processing program to manage the simulation results and obtained the geometry dimension changing information of heavy rail after straightening. It analysed the geometry dimension changing conditions of heavy rail after straightening. It has great reference value to improve the quality of heavy rail.
