Research on wear and grinding models of high-speed turnouts based on semi-Hertz contact

Abstract In order to reduce turnout rail wear, the paper establishes a coupled dynamics model and a turnout rail wear model that consider the true profile of the turnout rail, the vehicle’s continuous traction force while passing, and the operational resistance. Comparative analysis of various model...
