摘要
The article is devoted to studying the problems of stepping up the transport safety requirement sand reliability improvement of mechanical subsystems components of the rolling stock. The authors show that in the process of wheel-rail friction we deal with the formation of non-linear connections depending on a large number of nonlinear interrelated factors, dynamic parameters of the mechanical subsystems and environmental conditions. The methods of tribospectral identification and physical and mathematical simulation are used for studying and dynamic monitoring of the mobile friction systems. The application of integral estimation of amplitude-phase frequency characteristics makes it possible to identify and forecast the friction contact condition and its tribothermal dynamics.
