Experimental analysis of the oscillations of two-mass system with self-synchronizing unbalance vibration exciters

In this work the experimental researches of dynamics of a model of a chain-type two-mass oscillatory system with two unbalance vibration exciters are carried out. The method of smooth variation of the debalances speed is used to analyze the amplitude-frequency response of the model. The modes of synchronous rotation of debalances are studied depending on the control parameter – the frequency of the supply voltage. The power characteristics of the electric drive and the influence of the carrying body oscillations on the power consumed by the exciter are established. It is shown that the effect of adaptive self-synchronization of debalances occur in the mechanical system, when the oscillation modes of carrying body vary with the excitation frequency
