PYTHEAS Technology will present at the RASD2019

The objective of the PyDAMP project is to develop a hybrid mechanical suspension to reduce the vibrations transmission on a wide frequency band. The undesired vibrations are generated by small electric motors (few kilograms). A suspension with piezoelectric pillar developped by PYTHEAS Technology is compared to a conventional viscoelastic suspension in terms of performances in the audible frequency range. The principle and design of the piezoelectrical suspension are approached through an electromechanical model and a finite element model. The electromechanical coupling of the transducer allows the introduction of mechanical damping and electric damping with different shunts (resistor and negative capacitance).
