description: Â The subject of the gradate qualification work is: "Modeling the movement of a wheel along a section of a rail with surface imperfections".Â This work is devoted to the analysis of contact stresses that arise when a wheel moves along a section of a rail with surface defects.Â When a wheel passes over a rail section with surface defects, one can expect an increase in contact pressure, a change in the shape of the contact area, the appearance of several contact zones, and an increase in stress in the disk part of the wheel. Tasks that were solved in the course of the study:Â 1. Consideration of possible surface defects of rails and their causesÂ 2. Preparation of wheel and rail models in CAD systemÂ 3. Preparation of a finite element model in the ANSYS Workbench environmentÂ 4. Carrying out the calculation of the movement of a wheel along a rail with surface defects in a static and dynamic formulationÂ 5. Analysis of contact pressure and stresses in the disk part of the wheel.Â As a result, the values ââof contact stresses that occur when the wheel moves along the rail, on which there are some surface defects, were obtained, and it was concluded which surface imperfections can lead to further destruction of the rail.
