Dynamic loads of drive of suspended timbertransporting rope system with an electric motor are investigated. Developed a dynamic model of the electromechanical drive considering the changing of the electric motor’s moment during start-up and the resistance force moment. The changing of the resistance force moment is expressed through the changes in tension force of the pull-bearing rope systems in...
Resonant transverse bending vibrations of the band saw blade have been investigated taking into consideration variable in the time tension force of the blade and the external periodic perturbation. Amplitude of resonant vibrations of the band saw blade piece has been determined by the Bubnov-Galerkin method and basing on the idea of perturbation theory.
The radial-distribution function of the position of the arc in a plasmatron of an axial scheme with gas-vortex stabilization has been determined from the results of standard measurements of the radial pulsations of the projection of the arc. A model allowing explanation of the displacement of the distribution maximum from the axis of the discharge chamber with increase in the current has been proposed...
