Abstract:Based on the piezo shunt damping technology, a new type of vibration ring was designed with piezoelectric stack. The vibration ring can effectively reduce the vibration of the transmission system passing through the shaft and bearing to support. It can avoid the piezoelectric stack to bear tangential stress and increase the service life of the piezoelectric stack. A new passive control model of piezoelectric vibration ring was proposed. The complex stiffness of the vibration ring and the force transfer rate function of the system were derived. Three kinds of external circuit form were put forward. MATLAB program was used to optimize the parameters of electronic components in a shunt circuit according to the system force transfer function. Through numerical simulation, it was found that the peak value of the force transfer rate function of the system is obviously reduced after the installation of the vibration ring.
