  1. 1. Engineering model for curve squeal formulated in the time domain

    Författare :Ivan Zenzerovic; Chalmers University of Technology; []
    Nyckelord :tangential point-contact model; time domain; frictional instability; Curve squeal; rolling contact; non- Hertzian contact;

    Sammanfattning : Curve squeal is a type of railway noise that may arise when a railway vehicle negotiates a relatively tight curve. Squeal is common in curves of a radius lower than 200 meters. A single frequency dominates the radiated sound, which makes squeal a very tonal noise. LÄS MER

  2. 2. Time-domain modelling of curve squeal: a fast model for one- and two-point wheel/rail contact

    Författare :Ivan Zenzerovic; Chalmers University of Technology; []
    Nyckelord :two-point contact; non-Hertzian contact; dynamics coupling; rolling contact; tangential point-contact model; Curve squeal; time domain; frictional instability;

    Sammanfattning : Curve squeal is a type of railway noise that may arise when a railway vehicle negotiates a relatively tight curve. A single frequency, corresponding to a wheel mode, dominates the radiated sound, which makes squeal a very tonal noise. LÄS MER
