INFLUENCE OF PARTICLE SIZE DISTRIBUTION, ENERGY CONDITION AND REACTIVITY OF THE SPRAYED MATERIAL ON THE FORMATION OF SURFACE LAYERS NANOSTATE MADE OF SHAPE MEMORY MATERIALS (SME)

abstract 1211607021 issue 121 pp. 484 – 498 30.09.2016 ru 363
The article contains a block diagram of the mechanical activation process of multicomponent shape memory materials, taking into account the variety of influencing factors. We have proposed to evaluate the reactivity of the sprayed material using the energy criterion (energy intensity), determined by the additivity concept as an energy amount of the raw material and energy accumulated during mechanical activation. Power consumption of the raw material depends on the chemical and phase composition and is determined based on the similarity between the melting energy, plastic deformation and fracture on the thermodynamic characteristics and diagrams of the systems. The energy stored in the MA is determined on the basis of X-ray structural analysis. We have demonstrated that with increasing of grinding precision there is growth in the number of active centers, which enables nanostructurization of surface layers in high-velocity oxygen-fuel spraying (HVOF). According to the study, we have developed practical recommendations for effective implementation of mechanical activation of the shape memory material

TECHNICAL AND ECONOMIC PERFORMANCE OF VM32 MACHINE MULTI-COMPLEX

abstract 1171603073 issue 117 pp. 1129 – 1138 31.03.2016 ru 364
The article describes problems of economic growth of the Russian Federation, development of high-tech knowledge-intensive manufacturing industries on the basis of a fundamentally new technological order, creation and development of import-substituting production of engineering resources that relate to dual-use technology and are in the most demand by strategic organizations of machinetool, machine-building and military-industrial complexes (aircraft engineering, rocket and space engineering, shipbuilding and power engineering). We proposed some measures to improve the accuracy in the manufacture of complex and large-sized parts with weights up to 100 tons. Precision machining of the workpiece surface is directly dependent on the tooling, quality and quantity of the cutting tool (CT), as during the processing the CT wears and must be replaced. We have described the modernization of multi-machine complex and ways of increasing the accuracy, the change in the kinematics tool supply to increase the number of tools used in the processing. We made calculations of the new chain drive of the tool supply. The proposed modernization of the tools will increase the instrument amount that allows increasing the accuracy of manufacturing products. We have also made calculations of the economic effects of the tool supply modernization

RESEARCH OF THE DEHYDRATION PROCESSES OF BIOPOLYMER SYSTEMS IN POULTRY PRODUCTS

abstract 1211607045 issue 121 pp. 801 – 812 30.09.2016 ru 365
The article presents the results of the study of the ratio of the water fractions, which differ on binding energy with the biomaterial in the composition of poultry products having various fabric and polymeric structure. The authors used the method of differential scanning calorimetry. The objects for the research were experimental and industrial samples of poultry products. We prepared the experimental samples by wet thermal treatment of broilers heads and feet at the pressure of 0.24 MPa. The objects for comparison were the products of industrial production of poultry meat: the paste of chicken meat with multicomponent composition (minced chicken, pork fat, water, pork liver, onions, wheat flour, soy protein, emulsifying, the taste and flavor food additives, color correction supplements); natural canned meat "Chicken in the own juice" (GOST 28589-90). The analysis showed that the investigated samples (broiles heads, broilers feet, multicomponent paste) were characterized by the similar values of the mass ratio of the water fractions at three stages of dehydration, the relevant sections of the curves based on the degree of conversion of the substance α from the heating temperature in logarithmic coordinates. The results can be use in the development of formulations of food modules for the production of emulsified meat products from raw materials, subjected to preliminary heat treatment. We expect that the positive effect will be to increase the degree of utilization of secondary raw materials in the processing of poultry in primary production, expanding the range of foods enriched composition due to the natural raw material sources, improving sustainability of raw material base of processing companies

TO SUBSTANTIATE A VEHICLE SPEED WHEN CONDUCTING HARVESTING OF FIELD WORKS

abstract 1281704033 issue 128 pp. 455 – 465 28.04.2017 ru 366
A more efficient use of road transport can be reached both by increasing the carrying capacity of the car and the average speed on the road. Due to limiting the safe load on the axle of the vehicle, a more promising solution is to increase the average speed on the road. Restricting car traffic speed on the roads with asphalt-concrete surface is due to the traffic safety, defined as resistance, steerabililty, vibrations of steering wheels and braking dynamics of the vehicle. The first three factors are influenced by the functional characteristics of the suspension and the state of the road surface. The share of agricultural vehicles mealage on the roads with improved surface does not exceed 65%. Nowadays, 40% of traffic volume and 9% of transport mealage are due to the transportation from the field and to the field. The aim of this work was to study the vibrational load of the load-carrying system and the driver, as well as the vehicle speed during the harvest time. To carry out theoretical research we used mathematical model "vehicle-road" system proposed by V.P. Tarasik. As a result of research we obtained the dependence of the acceleration of the front axle on the vehicle speed. The results showed that the maximum acceleration of the front axle is observed at a speed V = 20 km / h, which corresponds to external influences 1.54 Hz (9.7 rad/sec). The peak values of the vertical acceleration amounted to 5.80 m/s 2. The correctness of the mathematical model was verified by comparing the results of theoretical and experimental research in the mode of uniform motion. The experimental determination of the vibrations of the vehicle sprung mass was carried out using the sound level meter and spectrum analyzer OKTAVA-101 AM, which is equipped with a vibrational pickup AP 98. The given calculations showed that the relative error of the results of theoretical and experimental research is 3.94%, the average value of an error at a confidence coefficient of P = 0.95 is 4.76%, which confirms the correctness of the mathematical model. The studies showed that if the speed is between 14 to 40 km / h, the vibrational load on the driver is from 1.42 m/s 2 to 2.82 m/s 2, that is 2.5 ...3.5 times the sanitary standards set by the requirements of the CH 2.2.4/2.1.8.566 - 96

OBJECTIVES AND METHODOLOGY OF CROSS-CUTTING DESIGN OF TECHNICAL SYSTEMS

abstract 1291705015 issue 129 pp. 185 – 198 31.05.2017 ru 366
The debate continues about reform of higher education In the country. We offer our point of view regarding the preparation of bachelors and masters on the direction of "Control of the technical systems". Department of automatic control systems leverages variable disciplines of specialization and optional subjects, forms a curriculum based on the needs of the business environment of the region or commissioned by a separate large enterprise. Students participate in the modules of project activities, form new and effective engineering solutions, to get skills of their practical implementation with regard to effectiveness, relevance and prospects of their further development. The production practice is very important in the preparation of bachelors and masters. To this end, the agreement on cooperation in the field of improvement of quality of preparation of students of SFedU concluded with the company RealLab (www.rlda.ru). It has allowed undergraduates to pass a work practice at the enterprise, custom-making thematic tasks of the enterprise on a contractual basis. Graduates of magistracy successfully find a job at the enterprise, providing thus strengthening of personnel structure. In this study, we propose a technique of teaching of bachelors and masters in "Control of technical systems". The main thesis is to use the technique of through projecting throughout the entire learning process. The trajectory of training is built for the student based on a module of project activity, training and production practices. The student studies the object, develops the control algorithm, programs it, chooses a set of technical means throughout the entire period of training with an exit to the protection of the final qualifying work

ANALYSIS OF QUALITY INDICATORS OF AUTOMATIC CONTROL SYSTEMS WITH NONLINEAR APPROXIMATION CONTROL LAW

abstract 1291705087 issue 129 pp. 1213 – 1223 31.05.2017 ru 367
The subject of research of this work was the study of the quality of control processes in a nonlinear automatic control system with an approximating the control law. In the known published works there are no results of such studies, which makes it difficult to synthesis a nonlinear control system for multimode objects in applied biotechnology, including technological objects of the agro-industrial complex. A comparative analysis of the quality of regulation in the transient and steady-state regimes is carried out. It is shown that the approximation method used for the synthesis of the nonlinear control law provides a linear dependencies in steady-state and close to them modes in combination with relay modes in transient regimes, which is a positive factor for improving the quality of regulation in multimode control systems. It does not necessary to determine the moments of switching the dependencies in the control law when changing modes

abstract 1311707031 issue 131 pp. 326 – 386 29.09.2017 ru 367
Assessment of barley for the blotch incidence is traditionally carried out by visual determination of leaf damage with the help of the available expert – phytopathologist , and with the account scales which allows to characterize a variety for resistance or susceptibility to the studied disease in field conditions. This method has a number of disadvantages that are proposed to be overcome by developing a new tool of a phytopathologist. The measuring tool of a phytopathologist should provide high accuracy of the assessment of plants damage caused by the disease, and the measurement procedure should be quick and easy. The aim of this work is to develop a mobile tool of a phytopathologist for quantitative fast assessment of winter barley leaves damage caused by blotch in field conditions. To achieve this goal the following tasks should be fulfilled. Objective 1: introduce the idea and concept of problem solution; Objective 2: justify the choice of method and solution tool; Objective 3: apply the selected method and tool to solve problems, i.e. to perform the following steps: – cognitive structuring of the subject area; – formalization of the subject area; – synthesis and verification of models; – improvement of the quality of the model and choice of the most reliable model – solving diagnostics problems within the most reliable model (classification, recognition, identification), decision support and research of the simulated subject area by studying its model. Objective 4: describe the effectiveness of the proposed solution. Objective 5: examine the limitations and disadvantages of the proposed solutions of the problem and prospects of its development by overcoming those limitations and disadvantages. The article provides a detailed numerical example of the solution of tasks on real data processed with the ASC- analysis and "Eidos" system
