Analysis and Design for Rapid Prototyping Mechanism Using Hybrid Flexural Pivots

Research output: Contribution to journalConference article

Abstract

High performance motion systems play an important role in modern technology especially in the area of metrology and process equipment related to the field of micro- and nanotechnology. The purpose of this study is to show how to properly design and fabricate prototyped mechanisms that integrate metal-polymer flexural pivots for precision motion applications. Finite element simulations are used to understand the mechanical behavior of these components leading to dimensions that minimize the work done by the polymer structures. Simulations indicate that, the penetration distance of the metallic inserts into the polymer structures should be around one half of the total insert length and that the profile of the pressure interference can be modified to enhance the performance of the composite structure. A cantilever beam with a flexural pivot is used to test the performance of the design and a piezoelectric-actuated four bar mechanism is prototyped and studied as a general application of these types of structures to the precision motion field. The methodology implemented in this work poses a simple and affordable way to fabricate, assemble and customize low-cost devices for precision motion application and it applies to both, systems fabricated by polymer and metal rapid prototyping technologies.
