Abstract Modelling principles and methods of laboratory accelerated tests of friction pairs and active systems in rolling and mechano-rolling fatigue are discussed in the paper. The system of criteria of similarity damage based on a statistical model of a deformable solid with dangerous volume is developed. It has been used successfully under volume and surface deformation, as well as in their interaction. The possibility of using the multi-stage loading method (Lokati) for the computational and experimental assessment of the contact rolling fatigue limit is shown, taking into account the similarity of the mechanisms of mechanical and rolling fatigue. The method of accelerated tests for rolling friction and mechano-rolling fatigue by multi-stage loading with a direct effect (change in time of the amplitude σa of bending stresses at a constant value of contact stresses p0 = const) and with a back effect (change in time of contact stresses p0 at a constant value of the amplitude of bending stresses σa = const) is described and implemented on a specific example. Examples of methods for accelerating tests by forcing their modes are also shown.
Keywords accelerated tests, modelling, active system, friction pair, wear-fatigue damage, rolling friction, mechano-rolling fatigue
