Calculation model of elastic deformations of a railway wheel in the contact zone with the rail, taking into account lubrication

The object of this study is the interaction of the wheel-lubricant-rail system. The subject of the study is elastic deformations in the contact zone of the wheel-lubricant-rail system depending on the properties of the lubricant. This paper proposes a model for assessing the influence of lubricant on wheel-rail interaction. The proposed method, with varying input data, can be used to determine the optimal lubricant for a specific region.
