Modelling and design of a flexure‑based precision positioning system

Abstract

The paper presents the model and design of a flexure-based 4 DOF precision positioning system for micro-positioning uses. The positioning system is featured with monolithic architecture, flexure-based joints and ultra-fine adjustment screws. The monolithic structure for the require movements has been optimized with Solidworks Simulation software package. The mathematical model for the output displacements of the positioning system has been verified by resorting to finite element analysis (FEA) using ANSYS software package. The established analytical and (FEA) models are helpful for a reliable architecture optimization and performance improvement of the precision positioning systems.
