  Simulation research on temperature field and stress field during rail ...

  202115 · Furthermore, through simplifying grinding wheels into heat sources, the temperature field of rail ground by a whole grinding train was investigated as well. The results indicated that the grinding temperature and the residual stress increased with the grinding depth and rotational speed, but decreased with the feed speed and radius of rail …

  Vossloh-CRCCE JV develops rail grinding trains …

  2016125 · The results indicate that in multipass rail grinding, a sequence of grinding passes – where the greatest grinding effort is applied on the earlier passes, with the last pass applying reducing levels of grinding effort – produces the highest conformance to the target grinding profile.

  Grinding force modeling and experimental verification of rail grinding ...

  2020110 · Abstract Many factors could affect the grinding force during rail grinding processes. Therefore, the grinding force modeling is necessary for predicting the grinding forces under different rail grinding parameter conditions. In this study, 3D models of grinding wheels were constructed based on the surface topographies of real grinding wheels.

  Controlling Strategy of Rail Grinding Mechanism for the Constant ...

  201997 · This paper focuses on design of controlling system for rail grinding mechanism to realizing constant grinding power. To this end, two controllers are designed to control the subsystems respectively. For the grinding subsystem, PI controller is employed to keep the grinding angular velocity of the motor to be constant.
