DESIGN OF COMPLIANT MECHANISMS WITH A SEQUENTIAL ELEMENT REJECTION AND ADMISSION METHOD
A Sequential Element Rejection and Admission (SERA) method to design compliant mechanisms with topology optimization techniques is presented in this work. This procedure, successfully applied to structural optimization problems, allows material to flow between two different material models: ‘real’ and ‘virtual’. This bi-directional method works with two separate criterions for the rejection and admission of elements to efficiently achieve the optimum design. Three benchmark problems are presented here to demonstrate the validity of the proposed method.
