Configuration design of compliant mechanism by infill structure generation method

Abstract

Part of the authors have proposed an infill structure generation method to obtain several suitable structural configurations, that is different from the structural optimization method that obtains a single optimal configuration. The method arranges the structural components fitted to the principal stress distributions for the grayscale optimum configuration obtained by SIMP method. This study applies the infill structure generation method to a compliant mechanism design problem. Through numerical examples, validity of the proposed method is demonstrated. Then, properties of several obtained structural configurations are compared.
