Byeloz'orov Y. Calculation and forecasting of friction features of interaction of working surfaces of wheels and rails

The thesis is denoted to the development of strategy of calculation of parameters of friction interaction of wheel with the rail on the traction factor criterion, actual pressures and areas of contact on the base of account running in the area of before contact a wheel micro-deformation processes. It was established that the deformation of the surface of the wheel in the area of before contact, connected with a change topographical features of the surface, influences upon the main friction parameters of interaction and requires an account in existing mathematical models. The theoretical description has been offered and experimental amounts and quantitative checking the processes has been executed. The main results of the work have found a using in designing the perspective locomotives.
