Design and Research of Micro-Displacement Amplifier Driven by Piezoelectric Actuator

Abstract:

Piezoelectric actuator was widely used in precision machinery as driving element used for their small size, high frequency, large resolution displacement and so on. A new micro-displacement amplifier driven by PZT is designed in this paper. The concrete machine parameters are studied out by finite element analysis. And the prototype is trial-manufactured. Experiential results show that the new mechanism has good displacement amplification performance and dynamic characteristics.
