Dynamics of a two-mass parametrically excited vibration machine

This paper presents the results of the investigation of the dynamics of a two-mass vibration machine whose operation is based on the excitation of multiple combinational parametric resonance. It is shown that the rational complication of the models at the expense of an increase in the number of degrees of freedom and allowance for nonlinearity makes it possible to reveal new dynamical effects and unveil additional possibilities for developing new power-saving machines and technologies.
