  • System analysis of technology objects and equipment for logging operations in order to synthesize new patentable solutions

    A system analysis of technologies and equipment for logging work was carried out in order to synthesize new solutions. It is based on the original functional and technological analysis of objects of logging technologies and equipment, worked out on a number of basic operations of timber industry. In the analysis, intellectual knowledge bases are being formed on technologies and equipment that are being improved or replaced, their role in the end-to-end technologies of timber production and related operations of these processes is taken into account. It is shown that it is advisable to harvest industrial wood with harvesters and forwarders during their cyclical work, to conduct forestry operations, to prevent and extinguish forest fires during the continuous movement of forest machines. As a result of the analysis, technical solutions were found for the technology of work and the structural elements of the multifunctional forest machine protected by patents.

  • Modernization of the container body for transportation and storage of spent nuclear fuel

    when analyzing container designs for transportation and storage of spent nuclear fuel, a tendency is revealed to improve them using the innovative potential of modern achievements in science and technology. The modernized design of the container is proposed, which includes a molded body with an internal volume under the cover. In the wall of the case, a neutron-protective barrier is poured from the material with a melting point higher than the melting point of the shell material and a thermal conductivity coefficient not less than that of the cast housing material. The barrier prevents the free passage of neutrons in the radial directions

  • Development of the network of forestry roads is the important factor of increasing economic availability of forest resources and forest use in the regions of the european north of russia

    the development of a network of logging roads and increasing the efficiency of its functioning is the most important factor in increasing the economic accessibility of forest resources and intensifying forest management in the regions of the European North of Russia. Substantial development of the network of forest roads is necessary to increase the availability of forests for continuous and selective cutting, thinning, reforestation. It is also necessary to improve the efficiency of the operation of logging road trains while exporting forests, to increase the degree of development of the allowable cutting area, to increase the level of forest fire safety of forests, and to prevent and extinguish forest fires.

  • Opportunities for the effective solution of technical-economic engineering problems during planning and optimization of wood transportation

    The developed calculation dependencies for determining the log truck movement indicators during non-steady and steady motion in different modes make it possible to solve technical-economic tasks with adequate accuracy and certainty during planning and optimization of wood transportation. During two-stage timber hauling a log truck based on MAZ-6312B9 has advantages in exploitation and technical-economic indicators in comparison with a log truck based on Scania R-420. There are opportunities for a rapid increase of passing ability of a log truck while using an active trailer. This provides the work of a complete log truck on a forest road, and also there is a possibility to eliminate two-stage timber hauling, with rise of efficiency and technical-economic indicators

  • Rising functional and technological efficiency of a log truck hydraulic manipulator

    One of the problems with exploitation of log trucks is damage to equipment during the process of transportation of wood material and during loading-unloading operations. The authors of the paper suggest equipping a log truck with an innovative protective butting device in order to increase reliability and work efficiency of the hydraulic manipulator. This device will allow aligning the sawn wood ends of wood products, and thus it will allow excluding a chance of protruding of sawn wood ends at an inadmissible scale which prevents forming a neighboring pack of wood products. The device will also allow excluding mechanical damages of a hydraulic manipulator by sawn wood ends of wood products being laid on a load platform. This will increase its reliability and will reduce the expenses on repair works.

  • Modern Russian forestry machine-building development trends

    The paper describes and analyzes the main development trends of Russian forestry machine-building in modern conditions. Russian forestry machine-building enterprises do not use presently available perspectives in import substitution in connection with the depreciation of the rouble. Neither do they use the opportunities for producing integrated multifunctional machines. Development and production release of forestry machines for assortment harvesting based on Russian-manufactured tractors fitted with technological equipment of foreign manufacture is the first step on the way of creating domestic vehicles of analogous purpose. These machines will be fully complete with home-produced technological equipment. This will allow reducing the costs on the production of these machines and on their timber-harvesting operations
