  • Resource conservation with snow removal in urban environments

    An analysis of snowplows in urban environments. Determined that the efficiency of snow removal from roads, sidewalks areas affected humps (bumps), borders, etc. In line with this analysis of structures working bodies (dumps), used in Russia and abroad, as well as analysis of patents. In accordance with the foregoing, all decisions on the management of blade can be divided: extra lever systems; modernization of hydraulic drive; use microprocessors; the combination of these approaches. Obviously, the use of processor technology is justified for high-tech machines, as a consequence has disadvantages in price, qualification of operators and maintenance personnel. For the modernization of existing equipment, at the moment, it is advisable to use the combined system using the lever and hydraulic drive systems. It is necessary to take into account the energy-saving technologies.

  • Models of integration cooperation of industrial enterprises: capitalization growth

    he article analyzes the different forms of integration and cooperation of industrial enterprises from the standpoint of the possibility of capitalization of their resource potential. Under-cap resource potential refers to the process of institutional modernization resource binding interactions of subjects for the growth of economic potential, both the subjects and formed or integration structure. Sources allocated resources capitalization growth industry. The main directions of the capitalization of resources for industrial enterprises operating in the composition of the integrated structure. It is shown how to attract more participants interaction (financial institutions, research organizations, government agencies) promotes the growth of capitalization. Proposed indicators to measure the level of capitalization of the resource potential of integration structures. It is concluded that the choice of form of integration cooperation should be defined as the interaction of the participants goals and objectives of regional development. The article is intended for a wide range of readers

    Keywords: industry, market capitalization, innovative capacity, integration cooperation, modernization, a synergistic effect of non-commodity development

  • Institutional support of the development of industries of the new stage of technical and economic development in reshoringa industrial production: the experience of state industrial corporations

    Changes in the structure of industry, caused by the process of the formation of a new phase of the feasibility of the global industry, and based on the creation and implementation in all areas of the industry of new technologies that provide higher added value. The development of new promising sectors of the feasibility stage of development should be accompanied by the creation of a new institutional structure to date, capable of providing a maximum concentration of innovation potential in terms of industrial production reshoringa. One of the most effective forms of institutional support for the development of high-tech manufacturing industries are state corporations to ensure the generation of technical, scientific and economic potential, the formation of a full cycle of "science-production" in a structural transformation of the industrial sector.

    Keywords: the new techno-economic paradigm, reshoring potential of innovative development, state-owned corporations

  • Development of calculation procedure of residual forming of type parts "bush" by electric resistance surfacing with a wire on outer surfaces

    The paper is concerned with development of calculation procedure of residual forming of type parts "bush" by electric resistance surfacing with a wire (ERSWW) using the finite element method (FEM) based on the theory of non-isothermal plastic flow. The adequacy of the design model is confirmed by the experimental data. The developed calculation procedure of residual forming allows to predict the possible axial and radial movement of type parts "bush" by ERSWW of outer surfaces in a single layer, that allows to make a decision on the feasibility and appropriateness of technology ERSWW during restoring of type parts "bush".

    Keywords: electric resistance surfacing with a wire; residual forming of type parts "bush"; finite element method; calculation procedure
