The purpose of the work is to create the foundations of the theory and design of resonant two-frequency vibrating machines with inertial vibrators in the form of passive car balancers. The research methods are theoretical substantiation, computer 3D modeling of dynamics, computational and field experiments. The project creates an approximate theory of new vibrating machines, based on the assumption that the autobalancer behaves dynamically as two independent inertial vibrators. This assumption simplifies the determination of vibration characteristics of new vibrating machines, and the calculation of their parameters. For the first time, the conditions of existence and stability of a family of established (almost) two-frequency movements are studied. For this purpose the generalized coordinates of masses of the vibromachine and total unbalance from cargoes are used. The accuracy of the approximate theory and limits of its application are estimated by search of more exact laws of vibrations of vibroplatforms. The laws of oscillating motion of vibroplatforms in higher approximations are determined. The value of corrections to the approximate laws of oscillations of vibroplatforms is estimated. According to the values of the amendments, a conclusion is made about the limits of application of the approximate theory. The results of the work can be used in various industries - mechanical engineering, construction, mining and more. Prototypes of new vibrating machines have been created. Their efficiency in production conditions is checked. It is established that in comparison with usual inertial vibrating machines new cars have on 8-20% more productivity at smaller on 10-25% energy consumption.
