description: The work is devoted to the asymptotic behavior of a system of two unbalancedvibration exciters (rotors) located on an absolutely rigid platform with one degree offreedom. The paper proposes a number of analytical criteria for self-synchronizationof rotors.The phenomenon of self-synchronization of rotors was discovered at the LeningradInstitute "Mekhanobr"in the late forties of the twentieth century. At the stand of theinstitute, a vibration machine with 2 independent debolance vibration exciters drivenby separate synchronous electric motors was tested for a long time. The rotors weremounted on a vibrating base and worked on average synchronously and in phase.Â Being mounted on a fixed base, the rotors would rotate at different speeds andrandom phases. The synchronous rotation was not disturbed even if the wire thatsupplies power to one of the electric motors was broken. This break was discoveredafter a few hours during which the machine worked normally.The paper proposes conditions for the parameters of two rotors that ensure theirsynchronous and in-phase rotation.Â
