Using the basic design of the conveyor with suspended belt and distributed drive, a series of numerical calculations was performed. As a result, the influence of friction and mass-dimensional design parameters of suspensions on the main technical parameters of the conveyor was established. Recommendations on the choice of rational parameters were formulated.

Quality of life evaluation was validated and applied according to the results of the survey of children’s and teenagers’ quality of life assessment index. The connection between the impact of anthropogenic factors and children’s and teenagers’ health complex index was detected.

In the article the method of calculating the optimum modes of processing of working surfaces of machine tool parts. Submitted by the expert quality parameter, which allows you to calculate the discrete values of machine tool surfaces quality parameters details. It is shown that mathematical formalization of finding the minimum stiffness of machine tools on the set altitude parameters treated workpiece surface roughness. These techniques allow the article to design the machine accessories and other items of industrial equipment with minimal cost of their production.

The presented method of calculation of the separation of solid particles from gas streams to multistage separation systems, consisting of a number of sequentially installed separational devices of various design and principle of operation. It is based on a separate analysis of the sequential processes of capture and transmission of individual fractions of solid particles of a polydisperse structure. The technique provides information about changes in particle size distribution of solids with the passage of the gas flow in the treatment system and allows you to specifically select the effective combination of different types of separators

The article presents results of comparative analysis of hydraulic crane-manipulator installations of mobile transport and technological machines and hydraulic manipulators of industrial robots. The comparative analysis is based on consideration of a wide range of types and sizes indicated technical devices of both domestic and foreign production: 1580 structures of cranes and more than 450 structures of industrial robots. It was performed in the following areas: functional purpose and basic technical characteristics; a design; the loading conditions of the model and failures in operation process; approaches to the design, calculation methods and mathematical modeling. The conclusions about the degree of similarity and the degree of difference hydraulic crane-manipulator installations of transport and technological machines and hydraulic industrial robot manipulators from the standpoint of their design and modeling occurring in them during operation of dynamic and structural processes.

The article considers regularities of the influence of forces of viscous resistance generated by the damper device in the cylindrical hinges of the nodes connect the links of the crane-manipulator units mobile transport-technological machines. The specified effect is considered on the efficiency of the damping of oscillations of the metal in the process of operation, due to the presence of increased clearances due to wear of the holes of the hinge eyes. It is shown that the force of viscous resistance should be considered in addition to the generated damping devices forces of elastic resistance, as the latter determine the effectiveness of damping in general. The main role of forces of viscous resistance is the dissipation of energy of an oscillatory turning movement of the mating parts of the metal structures due to oscillatory displacement of the hinge pin within the hinge gap until the complete decay of oscillations. Considered in relation to the crane-manipulator installing mobile transport-technological machines AST-4-A the effect of the action of forces of viscous resistance is almost not observed when the coefficient of viscous damping less than 0.01 MN·s/m, in the range 0,01…0,05 MN·s/m this influence begins to manifest itself more and more noticeable, in the range of 0,05…0,4 MN·s/m has a lot of damping vibrational displacement of the hinge pin within the gap, while the coefficient of viscous damping more than 0.4 MN·s/m oscillatory process becomes aperiodic with an almost complete attenuation in the range of one oscillation of the hinged finger.

The advantages and disadvantages of manometers with a resilient sensing element. A complete factorial experiment to determine the dependence of the metrological reliability of manometers. To investigate the effect of the level and duration of measured pressure overload full factorial experiment was performed. As the objects of experiment were new faultless manometers of the lower price segment of the most popular producers in Russia — «WIKA» (Germany), «Rosma (Russia) and «Meter» (Russia). Since all investigated manometers have a similar structure, but different materials and sensor gear, the experimental results may indicate a low quality of measuring system materials, used for the lower price category manometers. The methods of manometers protection against overloads.

The problems of landscape-ecological zoning landscapes of medium-high mountains of the Southern Urals, the analysis of the work of researchers in physical-geographical zoning and applied, developed and supplemented by methods of landscape-ecological zoning, the scheme of the landscape-ecological zoning landscapes of medium-high mountains of the Southern Urals.
