Goal. It lies in the synthesis of inertia-rigid parameters of two-mass resonance vibration machines taking into account the interference of rigid parameters in the oscillatory system. Topicality. The need for these studies is due to the fact that the vibration machine interacts with the parameters of the oscillation system, the main of which are inertial, rigid and power. If they are correctly calculated and implemented in the design of a vibration machine, it will be robust.
