Optimal Design for Compliant Mechanism Flexure Hinges: Bridge-Type. Micromachines 2021, 12, 1304. https://doi.org/10.3390/mi12111304 Academic Editors: Konstantinos Simeonidis and Nikos Maniotis Received: five September 2021 Accepted: 19 October 2021 Published: 23 OctoberAbstract: Compliant mechanisms’ design aims to create a bigger workspace and straightforward structural shapes mainly because these mechanical systems ordinarily have little dimensions, decreased friction, and much less bending. From that request, we created optimal bridge-type compliant mechanism flexure hinges with a higher magnification ratio, low anxiety by utilizing a flexure joint, and particularly no friction and no bending. This joint was developed with optimal dimensions for the studied mechanism by utilizing the process of grey relational evaluation (GRA), which is based on the Taguchi technique (TM), and finite element analysis (FEA). Grey relational grade (GRG) has been estimated by an artificial neural network (ANN). The optimal values were in superior agreement with the predicted value on the Taguchi method and regression analysis. The finite element analysis, signal-to-noise analysis, surface plot, and analysis of variance demonstrated that the design dimensions substantially affected the equivalent pressure and displacement. The optimal values of displacement had been also verified by the experiment. The outcomes were in good agreement having a deviation reduce than 6 . Particularly, the displacement amplification ratio was obtained as 65.36 occasions compared with initial design. Key phrases: optimization design; compliant mechanism; grey-based Taguchi method; artificial neural network1. Introduction For more than a decade, a lot of scientists and researchers have investigated quite a few types of flexure hinges to work with as the regular joints. Yong and Lu investigated the kinetostatic model with a 3-RRR compliant mechanism [1]. These joints could possibly be utilized as rotational joints for a 3-DOF (degrees of freedom) parallel mechanism with smooth and high-precision motion in micro/nanomanipulation work, wh.
