2.1. Simulaiton Model. According to reference , Han has previously established a 3D model of a 16# grinding wheel, the process of which is described below.First, a portable digital microscope (DM, KEYENCE, Osaka, Japan) is used to measure the end surface morphology of the grinding wheel, and it is deduced that the surface density of the abrasive grain is 0.27 mm −2.
The growth rate of rail surface (and subsurface) fatigue cracks (as shown in figures 1 and 2) is influenced by the level of contact stress between the wheel and the rail (refer to section 6.0). Figure 1 [5] shows the cycle of crack growth into the rail surface. Micro-cracks develop at the most stressed portion of the rail surface.
Jun 01, 2018· The grinding temperature has a significant impact on the status of grinding rail surface. When the grinding temperature ascends to 802 °C, visible grinding cracks and quenching cracks are observed on the rail surface. The tensile stress resulting from mechanical and thermal effects may cause the initiation of grinding rail surface cracks. 4.
