- Abstract
Abrasive belt rail grinding in open-loop structure (ABRG-O) has been recently proposed. However, its frictional heat leads to the risk of rail burning. In order to explore this grinding heat accumulation process, a 3D finite element model (FEM) of multi-abrasive scratching was established to analyse the grinding temperature field on the rail surface. The simulation results showed that the grinding temperature field was initially in the rectangular shape divided by chip grooves and then gradually became a strip shape with higher temperature in the middle. The increasing grinding force enlarged the magnitude and area of the temperature field. The force loaded at the centre of the grinding plate led to a more evenly distributed and longer high-temperature region. With the increase in chip grooves, the peak temperature rose. The study provides the theoretical basis for improving the grinding plate design and the intelligent setting of rail grinding mode.
