Design of Micro-displacement Mechanism Based on Flexure Hinges

Ying Liu

Abstract

Traditional mechanical micro-displacement mechanism can not achieve high precision,so a micro-displacement mechanism driven by piezoelectric ceramics was designed for precise positioning.The design of parameters for flexure hinge was described and the strength of material for flexure hinge was calculated.The static analysis of structures for micro-displacement mechanism was carried out based on finite element method in order to analyze the error between theoretical calculation and practice.The results indicate that the designed parameters of flexure hinge is correct.
