Introduction. The article is devoted to the export potential analysis of the electric power industry in the Russian Federation during the convergence period of the electric power complex into the Common Electricity Market of the Eurasian Economic Union.Materials and methods. The authors review the main indicators of the electricity sectors of the Eurasian Economic Union State Members. As a result of the analysis, it is revealed that the Russian electric power industry is the most large-scale and diversified industry in comparison with other Union state members. It is substantiated that the electric power complex of the Russian Federation could be fully provided with Russian fuel and energy resources, which give additional stability and competitiveness. Results. The evaluation of the electric power industry export potential of the Russian Federation couldn’t be made without determining the electric energy competitiveness, in which, according to the authors, it is advisable to include indicators of specific reference fuel consumption, loss in grids and cost of electric energy, both on the territory of the Eurasian Economic Union State Members and in the overseas market. As a result of the competitiveness analysis, it was revealed that Russian electrical energy may have certain competitive advantages in the common market and in foreign electricity markets.Discussion and conclusions. The main conclusions about the research results are made by the authors.

Poultry Farming

Currently, the modern poultry farms are located in regions with different climatic conditions. Thus, the component of the electric power being the base for combined heating and ventilating systems, lighting, and local heating of poultry farms, is great in power engineering on the territory of the Russian Federation. The analysis of energy costs of poultry farms showed that of the estimated options for reducing the cost of electricity for poultry farms, one of the most effective can be an alternative source such as the generation of own electricity. Naturally, for biological production with a continuous technological cycle (poultry farming, for example), seems to be replace about 45-55 % of the needs of the factory and serve as a reserve for the rest, but not cover all 100 % of needs.

The Mathematical Model

A hydraulic excavator is taken as the object to study. Considering the characteristics of slewing transmission mechanism of hydraulic excavator, the torsional vibration equation is established by the finite element method. According to the torsional vibration equation, the effects of the equivalent moment of inertia of working device on the torsional dynamic properties of slewing transmission mechanism are analyzed. Using the optimization theory, the mathematical model is built, which is by means of the equivalent moment of inertia of working device as objective function and by means of the position parameters of the working device as design variables. Based on the mathematical model, the optimization of torsional dynamic properties of slewing transmission mechanism is studied. Finally, a numerical example is presented.
