The method allows: to compose equations of steady motions of the system; find these movements; to investigate the conditions of their origin, existence and disappearance; evaluate stability of movements. The method is applicable both to the study of the self-balancing process and to the study of the Sommerfeld effect (the jamming of attached bodies - pendulums, balls, rollers...). It is shown that if the attached bodies are not specified (for example, the type of autobalancers balancing the rotor), then the method allows obtaining generalized stability conditions (occurrence of self-balancing), suitable for a rotor with various attached bodies (autobalancers of any type). This was used to: build a general theory of passive self-balancing; substantiation of the workability of the empirical criteria for the onset of self-balancing or the stability of the main movements, developed in current and previous studies; synthesis and research of the dynamics of resonant vibration machines operating on the Sommerfeld effect. A number of model problems were solved using the energy method. At the same time, the following were investigated: - modes of synchronous rotation and modes of jamming of loads (balls, rollers, pendulums) in a rotary system with an autobalancer; - the conditions for the occurrence of self-balancing within the framework of the spatial model of the rotor on isotropic elastic supports, which is statically and dynamically balanced by two or more passive self-balancers of any type; - dynamics of steady motions of one-, two-, and three-mass resonant vibration machines operating on the Sommerfeld effect.
