Description
Summary:The article examines the analysis of the state of adhesion of wheels to rails and substantiates variants of models of dynamic loading of the surface layers of wheelsets of locomotive wheelsets in the contact zone with brake pads. For the development of a dynamic loading model, a number of assumptions were made and, on the basis of the law of conservation of energy, equations for the vibration of the bending model were derived. On the basis of the revealed laws, the studied transient processes were modeled. The studied transient process is described by the Ostrogradski-Hamilton functional. For the obtained system of equations by the method of operational calculus, solutions were made with respect to the frequencies of natural vibrations of the bending model.
