This paper presents the design of a mechatronic system integrating iezoelectric multi-actuators, which is used to generate low-frequency vibrations to assist the forging process. With the aim of controlling the complete system, modelling using Energetic Macroscopic Representation is performed. A prototype with an electrical system is developed in a short term to validate the design. Finally, the preliminary experiments are presented with the corresponding simulation’s results.
