Abstract: Mechanical transmission noise and vibration will not only affect the health of personnel, but also pollute the surrounding environment. Piezoelectric shunt damping technology is a technology that uses the properties of piezoelectric materials to achieve mechanical noise control and vibration damping.In this paper, the piezoelectric shunt damping circuit is designed by using the characteristics of piezoelectric materials, and the optimal inductance and resistance values are obtained through the pole configuration method, and the control effect of the piezoelectric shunt damping technology on vibration is Verified by experiments, and the results show that the piezoelectric shunt damping technology has obvious advantages in vibration control. Through the research, we have a deeper understanding of the application of piezoelectric shunt damping technology in mechanical noise and vibration control, and provide a useful reference and guidance for the application of this technology in engineering practice.
