Abstract
It is found that the parameters of the negative capacitance circuit parameters have a great influence on the vibration amplitude of the piezoelectric damping vibration system with a negative capacitance circuit in experiment.The relation between the amplitude vibration of the piezoelectric damping vibration system with a negative capacitance circuit and the parameters of the negative capacitance circuit is derived.The simulations and experimentations are carried out.The theoretical simulation and experimental results show that the negative capacitance is closer to the capacitance of the piezoelectric patch
the effect of control is better.The series resistance is smaller
the effect of control is better.
