从轮轨几何接触的最一般情况入手,分析并建立轮轨接触几何通解的模型;考虑轮对的横移和摇头对几何接触的影响,并考虑轮对在曲线轨道上运动时,动态轨道即轨道曲率、扭率、轨头翻转、轨道倾角的动态变化及轨道几何不平顺的动态变化等对几何接触的影响;同时考虑左右轮轨型面不对称的情况;得出了轮轨接触几何通解的方程式并给出了部分数值模拟结果。
Starting from the most general situation of wheel-rail geometric contact, the model of wheel-rail contact geometric general solution is analyzed and established. Considering the influence of wheelset on the geometrical contact and considering the influence of wheelset on the curved track, The influence of the geometric parameters such as the curvature of the track, the torsional moment, the overturning of the orbit, the dynamic change of the orbital inclination and the dynamic change of the geometric irregularity of the track, etc., taking into account the asymmetry of the left and right wheel-rail surfaces; The equations are given and some numerical simulation results are given.
