Topology Optimal Compliant Microgripper

Abstract

This study proposes a MEMS microgripper design based on a compliant mechanism, utilizing the multi-input method to obtain greater output force and displacement. The compliant mechanism is very effective because the mechanism has flexible pieces that transmit force or deliver motion. The design domain is formed by the ground structure parameterization of the optimal topology. The goal is to obtain the optimal topology layout through computer simulation. This study combines insights from the topology optimization of the compliant mechanism and the piezoelectric microactuator to design a microgripper and to analyze outputs and displacement with different parameters under topology optimization.
