    Abstract
  • In order to improve the safety and riding comfort of linear metro vehicle, the structural characteristics of vehicle/track system was analyzed, and a dynamics vertical-lateral vehicle/slab track coupling model was developed.The random vibration characteristics of vehicle and track excited by track random irregularities were investigated, in which the time domain samples of track random irregularities were simulated by using trigonometry series.Track vertical and alignment irregularities were expressed as harmonic cosine forms, and the effect rules of their wave amplitudes and wavelengthes on the dynamic responses of the system were studied.The result indicates that the frequency distributions of air gap variation are mainly in low frequency field, ranging from 1.2 to 2.0 Hz; when the wavelengthes of track vertical and alignment irregularities are shorter than 10 m, the affect of the irregularities on wheel/rail interacting force, derailment coefficient and the reduction rate of wheel load is dramatical, which should be controlled seriously.
