Zelinskiy V.V. Failure factor evaluation of linkages for railway tamping machines
Failure factor evaluation of linkages for railway tamping machines
Zelinskiy V.V.
The paper deals with the relationship between fatigue damages of railway tamping machine linkages and provisions for their loading while performing regular operations. The damages may be accounted for low cycle fatigue caused by multiple short-term overloads. Mathematical modeling lets us obtain calculation formulas to estimate the effect of specific technological factors on forces resisting the machine movement. Machine components creating the largest resistance forces and loads in the linkage have been detected. The paper gives comparative load evaluation under the main technological factors such as the lift height of the railway when tamping and constant of friction in the roller grips contact with the rail. Technological and design recommendations have been given to reduce loads in the linkages and probable development of fatigue damages.
Keywords: damage, fatigue, part, resistance, load, factor, constant of friction, roller grip.

Experimental estimation of magnetic treatment effect on tool steels wear resistance
Zelinskiy V.V., Borisova E.A.
The article presents the results of an experimental study of magnetic-impulse processing effect on the wear of steel samples used for manufacturing cutting tools. Particular attention is paid to the methodological aspect of wear simulation in cutting process. Scientific basics of tribology are used, which provide maximum conformity with the actual cutting conditions in terms of wear and contact parameters. The description of experimental conditions and specific experimental methods are presented. They are used for obtaining new data on the effect of magnetic treatment on the wear of steels under study. Varying one of the factors of the magnetic field, that is the number of impulses, it’s possible to find out its significant effect on the wear value along with specifying the optimal number of impulses. A new interpretation of the reduction wear effect is presented. It is based on the adhesion-resistant surface secondary structure of a multiple-electron system. Its safety features are realized by the normalized energy distribution of the residual magnetic field and dissipated energy of tribocontact phenomena.
Keywords: magnetic treatment, sample, friction, wear, steel, impulse, tribosystem.

Zelinskiy V.V.
The topicality of researches devoted to interaction of surfaces in the process of friction on the small size of the actual contact area is substantiated. That interaction occurs into tribomates of many machines, and mechanisms as well as in the process of technological running-in. In relation to the plain bearings by the method of slip lines is shown, that at plastic deformation of micro-roughness is convergence and overlap of the deformed parts under them. The modeling of real interaction by the introduction of the hard cone with a certain sizes into plastic half-space, subjected to one of the conditions of plasticity is considered. The basic equations from the results of mathematical modeling of interaction of rubbing surfaces, obtained on the basis of the fundamental assumptions of the theory of plasticity are presented. Evaluation of the results of mathematical modeling on the correspondence of the results of the experiments, established by the method of x-ray structural analysis is given.
Keywords: deformation, surface, plasticity, modeling, micro-roughness, material, slip.
