NEW CONCEPT OF FORMATION OF VEHICLES RECYCLING
DescriptionNowadays, in Russia there is a problem of utilization of vehicles. The article has studied the various works proposed in the concept of creating "horizontal" system recycling vehicles. We have offered a different, "vertical" system concept, consisting of three subsystems, which together form a single waste management system

OPTIMAL PARAMETERS OF TECHNOLOGICAL LINE FOR LOADING TOBACCO LEAVES INTO CONTAINERS
DescriptionThe article presents the research results on parameters optimization of technological line for loading tobacco leaves into containers. The aim of the research was decreasing labor expenses on preparing tobacco for artificial curing. This was achieved by line modernization utilized for loading tobacco leaves into containers. We have also developed working parts of technological line for automatic loading of tobacco leaves into containers. Researches on weight studying of tobacco leaves of 3 sorts zoned in the Krasnodar region have been carried out. Dispersion analysis has not revealed weight differences between sorts, therefore, further researches can be carried for one sort. Optimization of working part for loading tobacco leaves into containers was carried by analysis of regression equation obtained by bifactorial experiment. Irregularity of leaf position was taken as optimization criterion. It has been discovered that optimal regimes: transporter belt speed v=2,8m/s, number of transporter’s double movements n=19 min1 can be used for uniform container loading by leaves. Researches on studying line capacity on leaves position irregularity revealed that maximal uniformity obtained when line capacity is 260 kg/h

Description
Getting the maximum number of dayold chicks largely depends on the disinfection of hatching eggs. Disinfection of eggs is important in the complex of veterinarysanitation activities carried out in poultry farms for the prevention and elimination of infectious disease in birds. The perspective of using ozone in the poultry industry is possible due to its advantages characterized in comparison with other chemicals. It was found that ozone has the special ability to retard the growth of fungi in the biological substrates, also slows the appearance of mold on the surface of the eggshell even at 90 % relative humidity. When making parameters and modes of electroozonation process of egg store poultry farms there were carried out experimental studies. After ozone disinfection of hatching eggs, total bacterial contamination of shell eggs decreased by 99.89 %. The relative error of the experimental values of the theoretical amount was 7 %. As a result of production tests we set quality parameters developed by the process of electroozonation egg store poultry farms: regulation time is 8 minutes, dynamic error is 0.9, overshoot rate is 4.5%, generalized integral RMS figure is 10.6 % . The findings suggest that there is a qualitative regulation of the distribution of ozone in the egg store

Description
Here we present a brief survey of the occurrence of noise in agricultural production while using agricultural machinery and machines with possibility of application of the newest technologies including informational ones. It is well known, that noise is a constant component of all agricultural enterprises and it often indicates the operational condition of equipment and technical culture of enterprises. This is true about both stationary production, such as elevators, grinding plants, feed mills, corn processing plants, and tractors and harvesters. It is natural that abovementioned mechanisms produce purposeful transformation of the movement. At the same time, any mechanism consists of separate parts that are flexibly joined with each other. In addition, it is due to this fact that the noise occurs. Thus, we should note that due to their design features and complexity of technology itself harvesters a priori are machines that create and produce noise. Noise reduction in machines and equipment is accompanied by increase of labor productivity. Thus, noise protection is an important issue. To reduce the noise a set of measures is applied but not all of them are efficient for selfpropelled machines, including harvesters. Besides, noise is one of the most important indicators of equipment quality, and in some cases, it can be the indicator of the technical level of a machine because it objectively displays inaccuracies in the manufacture of almost all parts. Therefore, noise control is an important problem that has social and economic value

COMPARISON OF SPECTROGRAMS OF THE MOST ACOUSTICALLY LOADED MODES OF OPERATION OF HARVESTERS
DescriptionNowadays the method of finite elements (MFE) is a standard method of acoustic analysis. It consists in finding the solution of the function on the maximum allowable quantity of piecewise continuous functions that are determined in allowed number of subdomains. The number of subdomains has a finite value but an unknown continuous value is approximated by the polynomial on each element that acquires specific values in the nodes. Polynomials can be various but all of them produce continuity of total value along its limits. Herewith because of technical features of the calculation process minimization of numbers of polynomials is required according to the criterion of acceptable precision. In the chosen COMSOL Multiphysics program model the range of frequencies under analysis is the result of the sum of 10 segments (subranges). Such a subrange is a minimal discrete value in certain conditions of calculation. Thus, the calculated value on this subrange can be considered as the result of calculation by means of using the bandpass filter with 35 Hz bandwidth. Because of this, we can draw a conclusion about changing the state change of the noise exposure on the combine operator with respect to the previous measurement according to the regulatory methodology. Hereinafter if the stated change of the noise exposure is found, measurements that are more precise are taken. On the basis of these measurements the head of the company receives recommendations either on verification of stated acoustic characteristics of devices and mechanisms of a harvester or on verification of acoustic ways of transmission of structural noise (noise created by devices that penetrates into the booth through the combine body), or on verification of noise isolation of the booth

FORECASTING THE AUTOMOBILE STATE ON THE BASIS OF APPROXIMATION OF ITS ELEMENTS PARAMETERS CHANGE
DescriptionThe article shows the necessity to consider the intercontrol result to forecast the automobile state and present it as a random value. It is pointed out, that the character of the automobile element parameter change is determined by the determined function and the criteria of this or that function choice. It is stated, that the variation coefficient serves as a criteria of approximation. Besides, the element resource variation coefficient is obviously more informative as it results calculations at the whole range of parameter change with consideration of this change character when the coefficient of the parameter change variation can reflect the approximation degree only on one or several sections. It is underlined that in a case of the parameter change functions approximation it is necessary to consider the automobile details breakin when one can see the short and sharp increase of the parameter change. Moreover, we have made a conclusion that the forecast error and intensity depend finally on the choice of the approximating function. The wrong choice of the function can bring to naught all the efforts to direct the safety margin and other parameters of the automobile elements. We have found out that the power function of thee parameter change is quite unique. This function coefficients having distinct physical sense are few. This shows the convenience of the wide use of the degree function for practical forecast. The approximation error of parameter change might be influenced (along with a selection of the function) by the accuracy of determining its coefficients. Finally, we have made a conclusion that it is very desirable after choosing and finding the coefficients of any approximating equation to convert it into one definite function and develop the forecast apparatus, tables, nomograms and so on for it. This is the only way of using the wide class of approximating equations when having relatively small math and other provision of the forecast

A REVIEW OF THE CURRENT ELEMENT BASE WITHIN THE CONCEPT OF SMART GRIDS
DescriptionEnergy complex of the country is a collection of electrical installations high and low voltage, producing, transforming, transporting, distributing and consuming electricity. A huge web of networks and more than 700 generating plants with a total capacity of about 230 GW [1]. Almost 90% of this potential is formed in a unified technical complex of the Unified energy system (UES) [2]. Now there is a deterioration of the performance of the sector. In comparison with 90mi years of XX century, more than 1.5 times increased power losses in the power grids. Significantly increased the proportion of obsolete electrical and auxiliary equipment, and the load on the network every day only increase. All speaks of the necessity of both local and global modernization of the electric power complex of the country and the creation of a new concept of consumption management and energy distribution in the network. In the framework of the energy strategy of the Government of the Russian Federation dated 13 November 2009 # 1715R, to improve handling and ensure reliable operation of electric power systems, wider introduction of flexible transmission system (FACTS devices) and improvement of systems of automatic emergency protection and dispatching control [1]. The development of electric power complex of the country should be in the way of intelligent networks. This is possible through the use of modern components that can make the process of managing "intelligent". In foreign literature, this term is called the Smart Grid
