Temperature field and material response as a function of rail grinding parameters

International Journal of Heat and Mass Transfer, 2021
Abstract Rail grinding is widely used as a technique to both reprofile the railhead in case of wear and to remove damage. However, grinding may lead to surface burning and the formation of a white etching layer (WEL). Taking into account the rail head position, the study established an analytical thermal model based on a non-uniformly distributed ...

Simulation research on temperature field and stress field during rail grinding

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2021
The rail grinding process generates a large amount of heat, which could lead to heat damage on the ground rails. But, the whole temperature field of rail ground by the grinding train has not been explored in detail. In the present study, finite element models of a rail and grinding wheel were established to simulate the rail grinding process.
