Документ Friction Unit of a Disc Brake Based on a Combination of Friction Materials(Allerton Press, Inc., 2019) Osenin, Yu. I.; Sosnov, I. I.; Chesnokov, A. V.; Antoshkina, L. I.; Osenin, Yu. Yu.The design of the disc brake friction unit is proposed, the basis for the creation of which is a combination of friction materials with different properties. As a criterion for the structural formation of a friction unit of a disc brake, it is proposed to use the initial equality of linear wear rates for all brake linings made of friction materials with different properties. It is shown that the use of a friction unit based on combined friction materials makes it possible to achieve new disc brake characteristics, compared to its traditional design. It is concluded that the proposed solution is promising.Документ Improvement of Adhesion of the Wheels of the Railway Carriage to the Rails by Means of Supply of the Scale and Magnetite Particles to the Contact Zone(Allerton Press, Inc., 2018) Sosnov, Igor; Osenin, Yu. Yu.; Osenin, Yu. I.; Chesnokov, A. V.; Sergienko, O. V.The article proposes a method to improve adhesion of the wheels to the rails of the railway carriage by means of supply of abrasive loose materials as an alternative to quartz sand to the zone of their contact: metal scale (Fe₃O₄ ) being the waste of rolling and forging, as well as the iron oxide—magnetite (FeO·Fe₂O₃) of the natural origin. The comparative assessment of efficiency of use of scale and magnetite was carried out in relation to quartz sand traditionally used for railway transport. The adhesion coefficient and wear intensity are used as comparison criteria.
