摘要：
To investigate the influence of wheel-rail periodic wear on the dynamic interaction force and contact creep characteristics, a vehicles-track coupled dynamics model was established for the flexible wheel-rail. Through the field measured harmonic wear of wheel and rail corrugation, three kinds of orbital incentives were obtained by the superposition of orbit uneven and three kinds of rail track, respectively. The wheel harmonic wear separately combined with three kinds of orbit excitations was taken as wheel-rail periodic wear condition. The dynamic characteristics of rolling contact for three kinds of wheel-rail periodic wear under low-speed and high-speed corrugating condition were compared and analyzed. The results show that no matter at low-speed or high-speed, the maximum wheel-rail vertical force appears in the rail corrugation section under wheel-rail periodic wear condition 1, and the maximum increase of vertical force under operating condition 1 is up to 76.16% compared with operating condition 3. However, the rail corrugation has little effect on wheel-rail lateral force. During the operation of condition 1, there are two peaks of high frequency vibration, and the vibration frequency caused by rail corrugation is higher than that caused by wheel harmonic abrasion. The influence of wheel-rail periodic wear on longitudinal creep effort is significant, but it has no dominant influence on lateral creep effort. During the operation of condition 1, the contact spot area maximized in rail corrugation section at both low speed and high speed, and its increasing rate increases with the increase of speed compared with that in condition 3. The residual corrugation in the wheel-rail periodic wear has little effect on the dynamic interaction between wheel and rail and the creep characteristics between wheel and rail. © 2021, Central South University Press.
