abstract 1241610052 issue 124 pp. 799 – 808 30.12.2016 ru 435
The flowsheet purification of exhaust gases in the Novocherkassk SDPP after the electrostatic precipitator on I-th stage of purification set group cyclone, on the II-nd stage of purification - baghouse. To determine the particle size distribution of fly ash, we selected ash from the transport network to the group cyclone, and the in a group cyclone, and in a baghouse. With the help of the microscope "Biomed- 3" we produced pictures of ash particles with different magnification. Granulometric composition of three selected ash samples were determined according to the mass content of particles of different grain size, expressed in percent relative to the weight of dry ash sample taken for analysis. For size fractions from 10 mm to 0.5 mm sieve method is applied without rinsing with water, for size fractions less than 0.5 mm sieve method is applied with water washing.

RESEARCH OF USEFUL POWER OF THE STIRLING-BASED ENGINE AND THE MECHANICAL EFFICIENCY OF ELECTROMECHANICAL ANALOGY

abstract 1241610059 issue 124 pp. 887 – 896 30.12.2016 ru 356
We have presented a table of analogues of mechanical and electrical quantities of a thermal power plant, which shows the relation between the useful power of the engine and mechanical efficiency, as well as the relationship between engine parameters and regime of its operation; we have also developed an electro-mechanical analogy, which helped to get the expressions linking the useful engine power with shaft speed, engine performance, coefficient of mechanical resistance and mechanical efficiency with speed, coefficient of drag and engine performance. Similar expressions were obtained for the relations of these variables with other sets of parameters. The article also shows corresponding graphs. The expressions for the maximum net power and corresponding speed of rotation was found. Thus, the efficiency isЅ. It is shown that in larger (compared with the extreme) speed, the mode is less efficient than with the smaller, for the same useful power. A method is presented to measure the important characteristics of the finished engine – motor operation and its rotational drag coefficient used in the resulting expressions

A MULTILEVEL SYSTEMIC APPROACH TO INTEGRATED OPTIMIZATION OF HARVESTING PROCESSES, TRANSPORTATION AND CLEANING OF GRAIN

abstract 1241610072 issue 124 pp. 1123 – 1146 30.12.2016 ru 533
A methodology for a multilevel system approach to integrated optimization of processes of harvest, transportation and cleaning of the grain during the harvest by the method of «Neveyka» has been developed. The main method of research - is a queuing theory of all components of the yield except straw. The System consists of 6 interconnected subsystems with their inputs and outputs, and its own optimality criteria. On the first level of optimization, the most efficient way of wheat harvest «Neveyka» has been proved. On the second level - the total duration of the harvest with allowance for 4-5 cultivated wheat sorts, each of which is harvested within 5 calendar days, was optimized. The third level proves the requirement of combine harvesters and transport vehicle. On the fourth level - the combinations of harvesting and transport units are optimized on the criterion of the minimum amount of the loss on the mutual expectations of harvesters and vehicles. The fifth optimization level proves the capacity of the reception station of the grain storage, where the main criterion for optimality is the least amount of losses on the mutual waiting time of the transportation vehicles, and the additional criterion is the minimum waiting time of vehicles in the queue. On the sixth and the final stage the specific annual economic effect (rub/ha or rub/t) from the implementation of the proposed technology is determined. It is established, that during the grain harvesting, transporting and processing of heap there are elementary or Poisson probability flows of requirements for service. The Representation of harvesting - transport link in the form of closed queuing system of independent harvesting unit. An approach to the justification of failure-free operation of a station for cleaning grain heap and storage of grain and chaff is presented

OPTIMIZATION OF THE MAINTENANCE SYSTEM OF STATION AND HARVESTING UNITS WITHIN THE FRAMEWORK OF TECHNOLOGY OF «NEVEYKA»

abstract 1241610073 issue 124 pp. 1147 – 1161 30.12.2016 ru 396
Using queuing theory (QT) for the new technology of harvesting of grain crops by the method of «Neveyka», the method of optimal designing of maintenance system and elimination of failures of units used in cleaning technology and post-harvest processing of grain has been considered. On the basis of a systematic approach, taking into account the probabilistic nature of the change of operating factors the methodical directions of validity test of the adoption of the Poisson distribution in the calculation of operating modes were substantiated to optimize maintenance level units and eliminate failures in the operation of the machines, the probability of failure-free operation of harvesting and transport aggregates. The probability of failure-free operation of each type of units used in the cleaning of grain depends on their number and intensity of service. According to the numerical value the probability of failure-free operation of units is equal to the probability of idle units for maintenance and elimination of failures. Since it is impossible to determine separately the value of the probability of failure-free operation for all types of units and all kinds of services at different operating conditions the generalized solution has been offered, this solution is applicable to any serviced unit during both the technical inspection and elimination of failures. By specifying the desired value of the probability of failure-free operation of harvesting units, according to their number we can determine the appropriate ratio between the average length of service and the average period of time between incoming service requirements (technical inspection and elimination of failures) from one unit

FEATURES OF THE DEVELOPMENT OF AN INFORMATION LEARNING SYSTEM

abstract 1241610075 issue 124 pp. 1182 – 1194 30.12.2016 ru 402
Nowadays, a necessary condition for progress in the field of information technology is wide adoption of standards and technologies of information systems used for hardware and software products. Building software of computing and information systems, based on the ideology of open systems, allows to successfully solve the problems of portability on platforms of various manufacturers, the problem of interchangeability of components and, most importantly, ensures the integration of devices and users in a variety of computing and telecommunication networks. It should be emphasized the fact that to date the successful implementation of any significant projects in the field of information and computer technology, management of information and telecommunications is not possible without coordination of development with existing standards in the field of information systems and, in some cases, the development of new standards. In the conditions of transition to integrated computing and telecommunications systems, the principles of information systems form the basis of technology integration, the establishment of sectoral, regional and national information infrastructures and their interactions on a global scale. So, we can conclude that the technology of information systems today is the working environment in which the priority is the development of information and telecommunication technologies, telecommunication and computer engineering

abstract 1241610078 issue 124 pp. 1229 – 1242 30.12.2016 ru 427
The article presents a staged scheme for granulation of solid fraction solids of fermented poultry manure (SF FPM) in an augered granulator. Granulation process of material has been reviewed in every stage of compression. The structural and mechanical properties of the pressable material were studied. It was revealed that SF FPM refers to pseudoplastic bodies, which when exposed to pressure exhibit anomalous properties. We present a rheological model of the motion of pressed materials in an augered granulator. We have modeled a mechanical model of actions at SF FPM. It was revealed that the compressible material at voltages generated in an augered granulator at the area of plasticizing was acting like an abnormal liquid. This liquid obeys the regularities of Newtonian liquids
