Modal Properties Tuning Analysis of Dynamic System with Piezoelectric Components

This paper explores the modal properties tuning of mechanical systems using piezoelectric transducers. The study focuses on piezoelectric shunt damping techniques, particularly Synchronous Switch Damping on Voltage (SSDV), to mitigate vibration and alter resonant frequencies. Simulations and experiments were conducted to investigate the influence of phase shifts and applied voltage on the system's dynamics. The simulation results indicate significant changes in the resonant frequency at certain phase shifts, while the experimental results showed partial alignment with the simulations, revealing challenges in electronics and the need for precise control. This research contributes to the development of adaptive vibration control technologies, enhancing the stability and lifespan of mechanical systems.
