  • Analysis of variance of dust emissions from aspiration systems cement manufacture with using improved experimental setup

    There presented paper presents the survey of industrial systems of aspiration and the results of analysis of variance of cement dust released from the equipment in this article. It was described the main technological processes, devices and related major sources of emissions and discharges of pollutants into the atmosphere in the cement factories in this paper. It was proposed a common generalized approach to determine the actual effective or hydraulic sized dust particles using by new experimental set up equipment to get high accuracy. It could be done using the results of analysis of variance (ANOVA) for sand’s dust and etc. bulk building construction materials. The development of new experimental set up equipment was ensured to decrease some negative influence of the old one. It was made a comparison changing cumulative distribution of the equivalent size of dust particles within aspiration schemes. I was fulfilled the comparison changing cumulative distribution of the equivalent size of dust particles after wet cleaners and inertial separation’s device (VZP) decreasing dust systems of aspiration schemes emissions exhausted in the atmosphere in the production of cement. The paper presents the ways to define cumulative distribution function depending of the equivalent size of dust particles of statistical processing the results of the analysis of variance by polynomial regression.

  • The main defects of case details of cars and ways of their elimination applied in car repair production

    Production of case details – the difficult technological process demanding providing with the expensive specialized equipment, high-precision gages and defining a product level of quality. In this regard, the nomenclature of new qualitative case details in the market is very limited. In designs of cars case details are present practically at any knot or the unit. For example, the case of a transmission, transfer case (at its existence) the block of DVS cylinders, cases of the main thing and wheel reducers, cases of hydraulic and pneumatic pumps, cases of distributing devices, brake cylinders and so on. In article the concept of a case detail is considered, influence of quality of production and technical condition of case details on providing a resource of cars is revealed. Main types of influences which influence case details in use of cars are listed. Classification of the main defects of case details of cars is given, and the most perspective ways of their elimination in car repair production are considered. The listed ways found rather broad application in car repair production, but with growth of scientifically technical progress, emergence of new materials and technologies need improvement and modernization. Improvement has to be directed on increase of ecological safety, material and resource economy, reliability of technological processes and quality of the received result.

  • Modern gravitational a continuous production apparatus for mixing bulk materials

    In this article shows the known constructions of gravitational continuous devices for mixing of bulk materials and the conditional classification of these devices. There is the problem of obtaining mixtures in cases when the volume-weighted amount of one component of the mixture is significantly greater than the second (with the ratio of their mass fractions of 1:10, and more). Typically, in the production for mixtures with a ratio 1:10 are used mixers centrifugal type, which operate in a periodic mode. The problem could be successfully solved using gravitational devices that operate in a continuous mode. The classification represented according to the design of mixers. The levels conventional classification for these mixers: (a) used or no additional mixing elements ; (b) the nature of their physical - mechanical properties.

  • A study of the options adaptive analysis of solutions to optimization problems on the basis of logics Reichenbach and Lukasiewicz

    One of the components of the optimization problem is a set of constraints describing the basic requirements for solutions. So as to find a solution that fully satisfies all the wishes of the experts, it is not always possible, the search area extends through analysis of semi-feasible solutions. The adjustment of the system constraints may contribute to changes in the structure and appropriateness of the decisions. The paper shows the ways to form a generalized membership functions of vague constraints of optimization problems based on the logics of Reichenbach and Lukasiewicz. It is known that for the same design procedures in some cases it is necessary to obtain accurate solutions, while others just get approximate solutions. Therefore, we analyzed the features of membership functions obtained using these logics. It is shown that by implication deny rules to allow logic-based Reichenbach membership function takes values equal to one if the value of the function allow rule is one, or if the value of the function deny rule is zero. By implication deny rules in allowing based on Lukasiewicz logic membership function takes values equal to one if the value of the function allow rule is greater than the value of the function deny rules. Therefore, it can be argued that when designing systems with increased reliability (precision) is more expedient to use the function implications for Reichenbach deny rules in a permissive compared with the same implication by Lukasiewicz. The implication deny rules to allow for the Lukasiewicz appropriate to use when designing subsystems that perform secondary functions that are not systemically forming, etc.
