This paper presents the design of a mechatronic system integrating piezoelectric 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...
This paper deals with the modelling of a piezoelectric stack actuator used to generate specific low frequency vibration waveforms to assist forging processes. Experimental results show that such waveforms reduce the necessary forging force during upsetting tests. The main problems which remain are defining the appropriate waveforms, predicting their influence on the process and the actuator and designing...
