“…Трибологический рейтинг смазочных композиций на основе смазочного масла и противоизносной присадки строился с помощью экспериментальной установки оригинальной конструкции [11]. Базой сравнения выступало смазочное масло М-16Г2ЦС.…”

“…Во время испытания истираемые шарообразный и цилиндрический образцы сближались, т. е. под действием износа опускался неподвижный образец. При этом, как подтвердили предварительные ходовые испытания в работе [11], подвижный образец -в силу лучшего режима смазывания и устойчивого теплового режима -практически не изнашивается, что дает основания к расчету диаметра пятна износа шарообразного образца как функции от величины его вертикального перемещения d = f(h). Диаметр пятна износа d = f(h) неподвижного образца под нагрузкой F является для каждой из испытываемых смазочных сред результатом трибологического испытания.…”

The paper presents the results of studying the influence of variable characteristics of lubricating oils for marine diesel engines (concentration of layered friction modifier in lubricating oil, viscosity of lubricating oil, contact pressure in the friction zone) on the tribological parameters of parts of the cylinder-piston group of marine diesel engines. There are considered the aspects of increasing the reliability and wear resistance of the cylinder-piston group of marine diesel engines when a layered friction modifier is added to the base lubricating oil in a concentration of 1.5 vol.%. There have been carried out the comparative tribological studies of M-16G2CS lubricating oil including an additive based on molybdenum diselenide. Dependences of the wear of parts of the cylinder-piston group of a marine engine on different parameters of the studied lubricants are shown. The wear rate of experimental samples in conditions of variable characteristics of lubricants has been studied. According to the tribological studies of lubricants and structural materials, the tribological rating of lubricating compositions containing M16G2CS marine engine oil as a base and a layered friction modifier - molybdenum diselenide as a tribologically active additive was built. The test tool for the antiwear ability of lubricants is a friction machine of an original design with abraded samples according to the “ball-cylinder” contact scheme. Mechanical mixing of the lubricating medium of “oil + additive” type on the RPU-0.8-55A rotary-pulsating unit was one of the variable parameters in the tests. The tribological efficiency of the studied antiwear additive varies depending on the type of mixing of the additive solution before adding to the base lubricating oil and makes 13-54% (the difference in the diameter of the wear spot of the sample) for mechanical mixing, and for rotary-pulsation mixing - 45-56%.

“…Diesel engine main bearings can run fasterF and bear a larger load [10][11][12][13]. Elastic deformation on the surface contact of bearings, as well as the bearings themselves, can affect oil film thickness, oil film pressure, and the force and power consumption of friction, thereby affecting the lubricating properties of the main bearing [14][15].…”

In this paper, flexible multi-body dynamics was coupled with elastohydrodynamic lubrication of main bearings to study the lubricating properties of diesel engine main bearings. Data of bearing forces for diesel engine main bearings under rated conditions and cylinder 1 misfired conditions were analyzed, to provide a basis for the tribology design of a main bearing friction pair and the system optimization of a diesel engine. The result showed that single cylinder misfire had a greater influence on the two adjacent main bearing loads and the axis orbits of the two adjacent main bearings, but less effect on the other main bearing load and axis orbits of the other main bearings.

The purpose of the study is: the impact of magnetic pulse processing on the performance properties - wear resistance and durability of parts of various units, machines, complexes. Method: the method is based on the use of the combined effect of magnetic fields on a mechanical engineering structure. The behavior of parts under the influence of strong magnetic fields is described. Result: the main advantages of the behavior of the processed material when exposed to a magnetic flux are determined. Conclusion: the use of magnetic influence on structural materials is considered a progressive method, which provides a number of advantages compared to other influences. This method allows you to change the structure of the metal itself, and therefore its physical and mechanical properties, which allows you to improve the performance characteristics of not only parts, but also the product as a whole.
