ДОСЛІДЖЕННЯ РОЗСІЯННЯ ЕНЕРГІЇ ЗА ДИСКРЕТНО-КОНТИНУАЛЬНОЮ МОДЕЛЮЮ ДВОМІСНОЮ ВІБРАЦІЙНОЮ СИСТЕМОЮ

In the work, the energy of the oscillation process was investigated according to the discrete model of the two-seat vibration system "working body of the machine - sealing medium". It was found that with a small dissipation of energy in the case of a force acting on one of the masses at a given amplitude of oscillations of this mass, the ratio of amplitudes of oscillations in the resonance mode is determined only by the parameters of the second mass and the ratio between the masses. The conditions for the effect of dissipation in the resonance mode at a frequency close to the partial frequency of the mass on which the external force acts are determined. At the same time, the difference between the inertial force acting on the second mass and the elastic force is not equal to zero. Therefore, the effect of dissipation is negligible. In the case of resonance at the frequency caused by the second mass, the role of scattering forces increases. The energy dissipation associated with the mass on which an external force acts has a significant effect on the frequency of the first resonance. The obtained research results are important information for the design of vibration machines of this class, including surface machines for laying concrete roads.
