A full information expression model for track irregularity based on stochastic harmonic functions in vehicle–turnout structure stochastic vibration analysis

Abstract Turnout irregularity significantly affects the stochastic vibration behavior of vehicle–turnout structures. This study proposes a fitting formula for the turnout irregularity spectrum and develops a turnout irregularity full information expression model (TIFIEM) using a stochastic harmonic...
