The problem of ensuring food security of the Russian Federation and sustainable development of the economy in the context of energy indicators and rates of human food consumption

In this article, the authors consider the problem of ensuring food security of territories as one of the areas of sustainable economic development. The authors' studies have shown that solution to this problem largely depends on the regulation at the state level of individually balanced human nutrition in order to ensure the optimal ratio of the components necessary for life.

INCREASING ENERGY INDICATORS OF HF TRANSMITTER WITH SINGLE-BAND MODULATION OF VOICE INFORMATION WHEN APPLYING AUTOMATIC MODE CONTROL

The article is devoted to the determination of the energy parameters of the transmitter when using automatic mode control for powering the output stages of single-sideband HF transmitters without taking into account losses in the controlled power supply.

Substantiation of the algorithm of information technology for energy monitoring of tractor engines

It is shown that it is necessary to control the energy indicators of automotive engines to ensure the operational efficiency of agricultural machinery in operational conditions. An algorithm for monitoring the energy indicators of the machine and tractor fleet of an agricultural enterprise is proposed, reflecting the main stages of obtaining, processing, storing and applying diagnostic information. Due to the timely assessment of the state of the equipment and the performance of the necessary maintenance, the efficiency of its work is increased.

Theoretical justification for the development of computer model of MDF structure and its milling process

The main parameter for determination of quality of MDF boardprocessing after milling is roughness of the surface. The well-known models of wood cutting are unsuitable for the assessment of this parameter, since they make it possible to draw only qualitative conclusions about the roughness, they do not allow calculating the numerical value. To calculate the roughness value, the model must take into account the structure of the material and the main parameters affecting the roughness. The purpose of this work is to substantiate the development of a computer model of the MDF structure and the process of its milling using the finite element method. The implementation of this approach will allow, according to the specified parameters of the cutter and modes of its operation, to determine the quality and energy indicators of the milling process from a theoretical point of view. As a result of the work carried out, a detailed theoretical justification for the development of a computer model of MDF structure and the process of its milling was given. Its implementation makes it possible to determine the quality and energy parameters of the milling process according to the specified parameters of the cutter and its operating modes.

Working machines state operational monitoring according to the parameters of the internal combustion engine

The authors showed that the imperfection of precision farming methods, methods of transferring energy from the tractor engine to the working bodies required the development of new methods for reliable and accurate identification of the soil and its properties, as well as the state of machine-tractor units. (Research purpose) To determine the actual energy and economic indicators of a working machine and unit reliably and promptly in the operating conditions of agricultural production by parameters closely related to the energy indicators of an internal combustion engine, the measurement of which did not require large costs. (Materials and methods) 24 indirect parameters reflecting the power and degree of engine load were used for the operational assessment. In this case, the angular accelerations of the internal combustion engine and the turbocharger rotor crankshaft, including those caused by the operation of individual cylinders, the working processes of the generator (their average and extreme values), as well as the amplitude-frequency spectra of these processes, and speed characteristics were taken into account. To improve the accuracy and reliability of the assessment of energy indicators, the authors selected the processes in the frequency and phase domains. (Results and discussion) The considered methods were tested in production conditions during the main processing of the alkaline-chernozem complexes of the Chulym district of the Novosibirsk region. The authors found that the use of a flexible machine-tractor unit based on an energy-rich tractor improved the quality of soil cultivation: the share of soil lumps less than 5 centimeters in size was 73-80 percent; the productivity of the tillage machine increased by 15-20 percent. (Conclusions) The authors proved that with the help of indirectly determined indicators of power and degree of load, it was possible to estimate the actual values of the energy and technical and economic indicators of the working machine and the unit, the quality of the assembly of the unit, the heterogeneity of the soil was much easier and cheaper than using the known force-measuring methods. It was found that the use of digital systems for automatic control of the unit using the indicated indicators made it possible to provide quite simply the setting of the optimal zone of energy modes.

Resource-saving Technical Means for Soil Maintenance in the of Orchard and Vineyard Spacings

The results of testing a resource-saving technical means for soil maintenance in the orchard and vineyard spacings are presented. The tests have performed according to two options for completing the chisel working bodies, that is to say, fitted with a chisel and sweeps, and fitted with a chisel without sweeps, on two backgrounds in order to determine the agro-engineering and energy indicators of the technical means.
