The article considers a vibratory conveyor with two inertial vibrators rotating in oppo-site directions and investigates the specific features of the formation of its oscillatory regime. A design scheme of the system was developed with account taken of the translational motion of the trough center of mass in the horizontal and vertical directions, as well as the small an-gular rotation of the body, which made it possible to represent the working process in the form of a planar dynamic model. Analytical relationships were obtained for determining the components of centrifugal forces, the resultant exciting action, and the kinetic and potential energy of the system, taking into account both the translational and rotational motion of the working member. It is shown that under the synchronous antiphase operating mode of identi-cal vibrators, a predominantly directed harmonic force is formed, and when its line of action passes through the center of mass, a stable translational motion of the conveyor is ensured. It was established that phase deviations caused by self-synchronization, differences in resis-tance torques, gravitational effects, and interaction with the conveyed material lead to the appearance of additional motion components, deterioration in transport uniformity, and may result in local material accumulation. The obtained results can be used for further analysis of the stability of the synchronous regime, evaluation of the permissible phase mismatch of the vibrators, and substantiation of the parameters of vibratory conveyors for transport and tech-nological purposes.
