Paper Title:
Design and Analysis of a Piezoelectric Actuator
  Abstract

Active materials are a group of solid-state materials whose geometric shape can be related to an energy input in the form of heat, light, electric field, or magnetic field. In the application of active materials to electromechanical energy conversion, electrical energy may be input to the material and the resulting deformation of the material can be used to move a load. The most common active materials used in actuators are piezoelectrics, magnetostrictives, and SMAs. In this paper, a piezoelectric actuation concept is presented that uses a new feed-screw motion accumulation technique. The feed-screw concept involves accumulating high frequency actuation strokes of a piezoelectric stack (driving element) by intermittently rotating nuts on an output feed-screw. The main parts of piezoelectric actuation such as clamp mechanism, rotary mechanism and “L type” driving mechanism are investigated. From the analysis, the deformation and stress of it are all under allowed value of 65Mn. The mathematics model of upside of rotary mechanism rotation motion is established. The results indicate that, the mechanisms of actuator all are satisfy the need of design
