Abstract
The synchronization of pneumatic vibroexciters operating under an autovibration regime with feeding pulsatile pressure has been investigated using aerodynamic channels. A mathematical model of nonlinear equations that describes the dynamics of two vibroexciters has been created and solved numerically. Results contend that the mathematical model helps in solving the dynamics of a mechanical system. The characteristics of both vibroexciters have been obtained; the regularities of time prior to the autovibration regime have been determined; the conditions of synchronizing vibroexciters have been shown; the effect of the parameters of feeding pulsatile pressure on the vibration shapes of the vibroexciter working body has been determined.

Kazimieras Ragulskis is a Lithuanian scientist and engineer. He created the scientific school of precise vibromechanics and vibroengineering. He is a Dr. (1954), Habil. Dr. (1963), Professor Emeritus, corresponding member of the Academy of Sciences of the USSR (Then of the Russian Academy of Sciences) (1987), member of the Lithuanian Academy of Sciences (1987), and Honored Inventor of the USSR (1987). K. Ragulskis, working with scientists under his supervision and who were his colleagues, created bases for theories of separate types of mechanical systems, inventions and patents, and innovations and their practical implementations. Original precise devices, manipulators, and robots, which are applicable in various branches of industry and science, were created. K. Ragulskis created a new scientific domain, namely, precise vibromechanics and vibroengineering. He created new and developed known effects and qualities of nonlinear dynamical systems, formulated scientific backgrounds of separate directions of this domain, created principles to create new systems, which were developed together with scientists under his supervision up to the applied scientific results for engineering practice. The obtained results are important for contemporary and future science and engineering. K. Ragulskis is the author and co-author of 28 monographs, 1750 inventions and patents, and hundreds of scientific works. He was a scientific supervisor or consultant of approximately 300 defended doctoral and habilitated doctoral dissertations.
Habil. Edmundas Kibirkštis is a Professor and Supervisor of the science group at Manufacturing Engineering Department of Mechanical Engineering and Design Faculty of Kaunas University of Technology. His areas of scientific interest include optical diagnostics, prognostication, research of machine dynamics, and research of vibrotransducer on air cushion with active links. He has published more than 250 scientific works in the fields of mechanical, materials, and measurement engineering. He is a supervisor of international and Lithuanian science projects.
