Abstract: In this article we consider three-links mechanism. We try to classify them according to L.T. Dvornikov’s classification of mechanism, which subdivide them into families, types, classes, orders and also into assurovi and notassurovi.

Abstract:

During the years of evolvement traditional modes of transport actually have depleted reserves intended for their further development. However, the growing population in major cities, massive migration, economic and social processes bring forward absolutely new passenger transportation requirements, which can’t be satisfied to the fullest extent nowadays, and in the nearest future they will serve as a powerful factor in its development. Fundamentally new technical solutions, which would tackle the whole complex of problems (security, a distance range, travel time, cost of transport; one-time investment, etc) more efficiently, are required. The use of separate track structures solves these problems most effectively.
Having analyzed various options of passenger transport complexes with separate track structures, the authors concluded that the track structure in the form of the elevated trestle of a pipeline type is the most rational for urban conditions.

Abstract: In the article the solution of the problem of heightening of efficiency of impact systems for the score of selection of rational shapes anvil blocks is reduced. Shape execution of anvil block in the form of two steps is offered - impact and cylindrical piston, which length steal up by "golden section" rule. Results of a finding of shapes of the impact impulses generated at direct blow on rods two-stage anvil blocks are reduced and analyzed.

Abstract: The possibility of using grooving to measure volume and type of residual stresses distribution in hard faced work rolls for cold rolling with high hardness of an active layer is described in this paper.

Abstract: Aspects of the structural synthesis of planetary gears without excess communications are analyzed. The possibility of creation of self-established multisatellite planetary reducers, by addition in the structure of gear of the group of links with zero mobility is proved. The solution of the problem of an equal distribution of loading on satellites is given. Computing experiments in the program complex «T-Flex Dynamics» are carried out. The new scheme of the planetary gear is shown.

Abstract: In paper, the problems of shared use of photovoltaic energy sources and energy storage devices for the implementation of sustainable energy-efficient operation of the power supply system urban electric transport are considered. The main attention is paid to a solution of the unevenness power curve problem of traction power supply system under the natural technological development of urban electric transport system. The conceptual solution of power supply structure on the basis of used capacities, with their substitution by the rational share of autonomous power sources capacities, is proposed.

Abstract: The article reports on the influence of magnetic field (B field) configuration of dual magnetron on carbon based films properties. The films deposition was performed by means of magnetron sputtering of carbon targets in argon plasma at total pressure range (0.1-1.6 Pa). The carbon films aren’t composed of chemical impurities as measured by Auger electron spectroscopy (AES). The B field configurations affect to a greater extent on mechanical properties and don’t have weighty impact on deposition rates. For «mirror» B field, the films hardness (H) is a higher. The rise of Ar pressure results in a decrease H from 20 to 9 GPa. It is peculiar to a-C and ta-C films. The effect of B field configurations on elastic module (E) is shown in higher pressures.

Abstract: Attention to oil shale processing as unconventional energy source grows significantly. Electrical discharge phenomena application allows creating new efficient technology. Dynamics of PD basic characteristics of voltage in oil shale is described in this paper. Thermodestruction with abnormally high rate is occurred and caused by PD activity. Critical PD incept under low electrical intensity due to oil shale porosity, anisotropy and heterogeneity. PD induce treeing with following electrothermal breakdown. Organic content has influence on electrical discharges phenomena in oil shale. Therefore, the detailed study of PD, treeing and breakdown in oil shale allows developing an efficient method of inferior solid fossil fuels processing.

Abstract: The equipment for plasma processing with specific area of application – production of building materials – is proposed. For the proposed equipment the examination of possibilities is carried out. It was shown that plasma processing significantly affects the components of concrete – portland cement, fine filler (silica) and water. The treatment of portland cement leads to crystalline hydrate shell destruction and removal of chemically bound water. This, in turn, leads to the increase of strength by 15-20%. Plasma processing significantly changes the state of the fine filler. The total surface area of such a filler decreases due to flash-off effects. In Raman spectra all strong peaks of crystalline quartz disappear, and amorphization of quartz takes place after processing. If both cement and fine filler are processed than strength can be increased by 30%. By means of plasma processing of water it is possible not only to enlarge the strength of mortar, but also to increase the rate of curing. The improvement of properties is probably due to changes of hydration completeness in case of activated water.

Abstract: The plasmodynamic synthesis was conducted in the electric hypervelocity pulse jet of carbon-silicon electric discharge plasma influenced on a copper target in an argon atmosphere. Some samples of a powder product with a high content of β-SiC were produced. The results of the experiments made at different levels of supplied energy were compared. It was shown that the sizes of crystals grew, when the energy of a plasma shot increased.
