A two-degree-of-freedom, self-exciting pneumatic vibroactuator was investigated. The feature of this vibroactuator is that, along with the sliding-reciprocating movement of the working body along the axis, it also rotates about this axis. A new mathematical model of this vibroactuator is presented and solved using numerical methods. Comparisons of the results of numerical and experimental studies are described. The analyzed vibroactuator, supplemented with extended functional capabilities, is established for use in intensifying technological production processes.
