Account of additional factors for damping torsional oscillations [PDF]
HeliyonSome parameters are influenced by the turbine unit's torsional oscillations. The fundamental comes from damping these oscillations, which are brought on by a departure in the turbine blades' speed from the device's prediction of the steam volume, and ...

Chaotic Oscillations of a Kinematically Excited Flat Shell During Geometrically Non-linear Deformation [PDF]
Journal of Mechanical Engineering, 2019 We study the forced oscillations of a cantilevered flat shell of constant curvature. These movements are excited by a kinematic periodic embedding motion. To describe geometrically non-linear deformation, the non-linear theory of Donel shells is used. To

Solar flares with sustained gamma-ray emission and some characteristics of high-energy proton fluxes
Solar-Terrestrial Physics, 2023 The first part of the work presents the results of numerical experiments with the magnetohydrodynamic model of “shallow water” to assess the degree of influence of the magnetic field on the development of instabilities conditioned by a combination of ...

Torsional oscillations of armature shaft of generator of main diesel locomotive in diesel start-up mode [PDF]
E3S Web of Conferences, 2023 The article considers a mechanical model of torsional vibrations in the starting system of a diesel generator (DG) with two concentrated mass moments of inertia and a previously unaccounted factor of torsional vibrations between the traction generator ...
