“…For instance, the papers [11] and [12] consider the implementation of such exciters for actuating various construction and road-building machinery, snowplows, etc. The possibilities of developing multipurpose adjustable planetary-type vibration exciters are thoroughly studied in [13,14]. The paper [15] is focused on investigating the resonance effects that occur during the operation of a vibratory system actuated by the planetary-type exciter.…”

Vibration exciters are of most important units of any vibratory equipment defining its design peculiarities, operational features, functional purpose, and performance characteristics. Among a great variety of vibration exciters, the unbalanced rotors are of the most widely used. The present research considers the possibilities of providing specific motion trajectories of the vibratory machines’ working members with the help of the planetary-type vibration exciter. The methodology of this study is divided into two main stages: deriving motion equations of an unbalanced mass located on a planet gear and analyzing the possibilities of generating rectilinear, elliptical, and circular motion paths by choosing the appropriate geometrical parameters of the planetary gear train. The results of the performed kinematic analysis are presented in the form of the unbalanced mass trajectories, velocities, and accelerations at different design parameters of the planetary-type mechanism. The main scientific novelty of the present study is substantiating the possibilities of using the single-degree-of-freedom planetary-type mechanism for generating the controllable motion trajectories of the unbalanced mass of an inertial vibration exciter. The obtained results can be practically implemented while developing novel adjustable drives for various vibratory equipment, particularly compactors, sieves, screens, and conveyors.

“…The paper [6] analyses the dynamics and substantiates the occurrence of the self-resonance operational conditions of the symmetric planetary-type vibration exciter. In [7], the author proposed the enhanced design of the vibration exciter allowing for generating the rectilinear (directed) oscillations. The planetary-type adjustable exciter with two unbalanced rotors synchronized by the chain transmission is studied in [8].…”

Vibration exciters are of the most important parts of vibratory technological equipment. Among a great variety of exciters, the inertial ones are currently the most widely used due to their design simplicity, well-studied control techniques, and relatively large efficiency. The present paper deals with a prospective type of inertial exciters based on a planetary mechanism. The main purpose of this research consists in substantiating the possibilities of providing triangular, rectangular, hexagonal, and other paths of oscillations of a single-mass vibratory system driven by a symmetric planetary-type vibration exciter. The mathematical model of the system motion is developed using the Euler-Lagrange equations, and the following numerical modeling is carried out with the help of the Runge-Kutta methods integrated in the Mathematica software. Virtual experiments are conducted in the SolidWorks software using the 3D-model of the vibratory system. The obtained results are presented in the form of time response curves and motion paths of the oscillating body under different operational conditions. The major scientific novelty of the paper consists in substantiating the parameters of the symmetric planetary-type vibration exciter allowing for generating triangular, rectangular, hexagonal oscillations of the single-mass vibratory system. The obtained results can be effectively used while designing new and improving existent vibratory technological equipment, e.g., conveyors, screens, feeders, sieves, etc.

“…Тем не менее, задача конструирования вибрационных динамических систем с генерируемой силой воздействия, обладающей высокой степенью направленности, остается актуальной. В работе [8] автором была предпринята попытка обоснования конструкции вибровозбудителя, сила которого направлена в заданном направлении выбранной оси. Тем не менее особенности конструкций и зависимость от времени производимой силы ограничивают круг технических задач, в рамках которых может быть применена конструкция.…”

Аннотация. В работе рассматривается техническая задача построения генератора периодического динамического воздействия высокой степени направленности, основанного на использовании сил инерции. Конструкция предлагаемого в работе устройства, преобразующего вращения кривошипа специального вида в качание пары массивных дебалансов, допускает реализацию силового воздействия, направленного вдоль выбранного направления выделенной оси. Зависимость полученного воздействия от времени носит гармонический характер, выгодно отличая его от существующих конструкций подобных устройств.
