This paper investigates the self-synchronization of mechanical vibrators having multidegree of freedom which occurs at resonance. It is shown that all the vibrators rotate with the same mean absolute angular velocity, in spite of the absence of any direct connections between their rotors. Generally speaking, there exist a steady rotation which is associated with the mechanism whereby a Hula-Hoop may be kept in rotation by an oscillatory motion of support. The generating phase angle between the rotation of unbalanced rotors and steady state vibration of the system are analyzed in detail.
