Abstract

By using the vehicle-track interaction model and the wear calculation model, the development characteristics of rail profile wear and the longitudinal characteristics of rail wear development of the track-vibration-absorber fastener tangential track at different passing speeds were analyzed. The results of rail profile wear analysis show that with the increase of iteration times, the wear ranges and wear depths of left and right rails at the corrugation trough/crest position are close. Meantime, the wear depths of rail profile and wave depth amplitudes at the corrugation trough/crest position in discrete passing speed modes are significantly lower than those in constant passing speed mode. The results of rail longitudinal wear analysis show that with the increase of vehicle running times, the characteristic frequencies of corrugation do not change under different passing speed modes, which reflects the fixed frequency feature of corrugation, and the irregularity levels corresponding to characteristics frequencies of rail longitudinal wear under the three passing speed modes show a decreasing trend in turn. Compared with the constant passing speed mode, the discrete passing speed modes can significantly decrease the rail profile wear and the development degree of rail wear at the characteristic frequencies.
