From the analysis of vibration generating machines, made on the basis of experimental data and virtual models, closed cyclic trajectories had been obtained. In this case the motion is produced using two generators with non-equilibrated masses while the machine body is supported by special rubber elastic elements with fixed mechanical characteristics. In order to increase the domain of operation of such machines and also to improve their functional capabilities the authors propose a new machine structure which uses pneumatic cylinders as actuators but in the same time as supporting elements with controllable mechanical characteristics. A virtual model of this structure had been developed and tested, and the test results are presented together with conclusions on the new structure’s behavior. The virtual model, allows the analysis of mechanical parameters (rigidity) of a pneumatic cylinder in order to establish the controllability of the supporting element. In order to obtain the desired cyclic trajectories the inverse kinematic analysis had been developed, obtaining the displacements at pneumatic cylinder level.
