  1. 1. Modelling of wheel/rail interaction considering roughness and discrete irregularities

    Author : Astrid Pieringer; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vertical wheel rail interaction; railway noise; roughness; non-Hertzian contact; time domain; discrete irregularities;

    Abstract : The interaction between wheel and rail is the predominant source of noise emission from railway operations in a wide range of conventional speeds. On the one hand, this wheel/rail noise concerns rolling noise and impact noise caused by the vertical interaction excited by roughness and discrete irregularities of the wheel/rail running surfaces, respectively.
