Ensuring the Operability of the Hinge Coupled with the Turning Mechanism of the Loaders and Dump Trucks Dinara Myrzabekova, Marek Mlynczak, Murat Muzdybayev, Alfiya Muzdybayeva International Review of Mechanical Engineering, 2022 The article considers the problem of ensuring the operability of articulated units of load haul dumpers. The hinge units were found to have an insufficiently reliable design and lack technical state controllability. It was identified that the pivot skew assembly units used in load haul dumpers based on articulated truck frames are the least reliable design elements. Tests and experiments have proven that the worn-out hinge units tend to dismantle from the vehicles when exposed to vibration causing the pin to come out from the coupling. This results in critical vehicle failures caused by the loss of the unit assembly integrity since the unit ensures vehicle safety. Certain technical design solutions aimed at improving the operability and controllability of the hinge assembly. This article reviews a concept method based on the Maintenance 4.0 approach for managing operability and reliability of load haul dumpers.
Functional Surface Layer Strengthening and Wear Resistance Increasing of a Low Carbon Steel by Electrolytic-Plasma Processing Kuat Kombayev, Murat Muzdybayev, Alfiya Muzdybayeva, Dinara Myrzabekova, Wojciech Wieleba, Tadeusz Leśniewski Strojniski Vestnik Journal of Mechanical Engineering, 2022 The modified technology for strengthening the surface layer of low-carbon steel for machine components by electroplasma processing is proposed. This technology is to be used as an alternative carburizing method with subsequent hardening. The developed technology of strengthening by the proposed method is based on the author’s invention. The parameters of this process are given, resulting in a thickness of the reinforced surface layer of 1000 µm to 1700 µm. An increase in microhardness of 1.5 to 2 times (compared to the initial state) was observed. With hardening, chemical modification of the material’s surface layer occurs. The microstructure of the treated surface of the steel samples is characterised by a dark modified surface layer: a fine needle-like structure of martensitic origin under the dark layer transforms into an initial perlite-ferritic structure. The advantage of strengthening based on the electrolytic plasma processing consists of low energy consumption at high hardening speeds and the possibility of local processing of surface areas, especially large parts of complex shapes. In addition, the proposed surface treatment method using electrolytic plasma processing (EPP) not only achieves a smooth surface but also improves the service qualities of the components, specifically wear resistance.
Preliminary experimental research of tribological properties of bus brakes friction linings M.S. MUZDYBAEV, A.S. MUZDYBAEVA, V.V. ROGOVSKIJ, D.M. MYRZABEKOVA, A.B. ELEMES, Wojciech WIELEBA, Tadeusz LEŚNIEWSKI Tribologia, 2021 Experience gained from the use of buses in urban conditions showed that the working conditions of friction elements of the braking system, ensuring traffic safety, are associated with high loads. This leads to the intensive wear and premature replacement of the worn friction components, which reduces the overall reliability of the brake system and road safety. On the other hand, the friction linings of brake mechanisms may act as abrasives that cause the wear of brake discs or drums. Their replacement during operation is associated with a significant increase in the cost of spare parts. Therefore, it is assumed that the determination of the tribological properties of the brake linings in the brake mechanisms, before their exploitation, will increase the efficiency and safety of the vehicles’ operation, which justifies the choice of the research subject matter for its real and practical significance. The paper presents the preliminary results of the research into the main elements of the brakes in a city bus on a test stand mapping the real working conditions. For the testing, brake shoes of different manufacturers were used. Their tribological characteristics, reasons for their wear, and operational recommendations were determined.
