  • 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

  • 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.
