It is known that piezoelectric material shunted with external circuits can convert mechanical energy to electrical energy, which is so called piezoelectric shunt damping technology. In this paper, a piezoelectric stacks ring (PSR) is designed for vibration control of beams and rotor systems. A relative simple electromechanical model of an Euler Bernoulli beam supported by two piezoelectric stacks shunted with resonant RL circuits is established. The equation of motion of such simplified system has been derived using Hamilton’s principle. A more realistic FEA model is developed. The numerical analysis is carried out using COMSOL® and the simulation results show a significant reduction of vibration amplitude at the specific natural frequencies. Using finite element method, the influence of circuit parameters on lateral vibration control is discussed. A preliminary experiment of a prototype PSR verifies the PSR’s vibration reduction effect.

In the paper, the problem of negative resistance has been studied. Considered systems are limited to mechatronic discrete structures that contains mechanical part and piezoelectric actuator in form of stack, connected to external electric network that include the resistance elements which can have and receive negative values. The study have been done based on examples of branched structures, received as a result of solving the reverse task, and is aimed for parameters, limits and constrains evaluation. The paper extends possible applications of piezostack actuators and applied configurations that utilize negative resistance for vibration control.

The passive vibration control is a very effective measure to gear system. But there exist some limitations. This paper viewed the development of the passive vibration control of gear system, and researched the damping characteristics of the friction dampers and viscoelastic dampers intensively. Firstly, the limitations of the existence passive damping technology are pointed out. Secondly, the feasibility and validity of piezoelectric shunt damping is guaranteed through experimentation on the gear system vibration control. Thirdly, a new hybrid damping, piezoelectric- viscoplastic material damping, is proposed, which extracts the advantages of piezoelectric shunt damping and viscoplastic damping.
