THEORY ANALYSIS AND TEST RESEARCH OF CHINESE MAIN TRACK IRREGULARITIES PSD

Abstract

Abstract: On the basis of the coupling thought of vehicle and track is applied, the track vertical profile, cross-level, alignment and gage irregularities are regarded as stationary ergodic Gaussian random processes. The vertical and lateral random vibration of vehicle and track is analyzed; the safe manage limits of high speed railroad track irregularities in the 250 km/h velocity field are calculated; at the same time, the difference and relation of Chinese main track irregularities PSD and overseas typical track irregularities PSD are discussed.

Key words: Dynamics emulation, Experiment study, Obit spectrum, Random vibration
