Abstract—

The article takes a new look at the reasons for wheel wear in a wheelset. The basic provisions of theoretical mechanics are used to substantiate the change in linear velocities of wheels in the wheelset at rail joints, which leads to lateral wheel drift and additional strain on the wheel crest, one of the main causes of different types of wear phenomena. At the same time, the amount of wear increases by an average of 23%. In addition, it has been found that when wheeled pair moves at joints, it leads to a vibrational process that also negatively impacts the wear intensity. The proposed theoretical dependences make it possible to quantify the force pressing the wheel crest to the rail to subsequently assess and predict its wear magnitude, which has practical significance at the operating and repair stage of rolling stock.

车轮滚动磨损问题的新认识

摘要—

本文重新审视了轮对中轮毂磨损的原因。使用理论力学的基本规定来证实轮对中轮对在轮毂处的车轮线速度的变化，这会导致车轮侧向漂移和车轮顶上的额外应变，这是不同类型的磨损现象的主要原因之一。同时，磨损量平均增加了23％。此外，已经发现，当轮对在接头处运动时，会导致振动过程，这也对磨损强度产生负面影响。所提出的理论依赖性使得可以量化将轮辋顶压到轨道上的力，以随后评估和预测其磨损量，这在机车车辆的操作和维修阶段具有实际意义。
