Design and Analysis of Compliant Gripper Mechanism using Topology Optimization

Abstract: Compliant mechanisms have been designed for various types of applications to transmit desired forces and motions. It also focuses the active research, because of the stability, robustness and ease of manufacturing endowed by their unitized construction. The objective of the proposed topology optimization method is to maximize the output displacement of the analyzed compliant mechanism at the same input condition, which is equivalent to maximize the Geometric Advantage. Matlab codes used for topology optimization. For displacement and stress analysis, finite element based ANSYS software used and compared with experimental values. The analysis domain is a two-dimensional plane, and the two-dimensional loading condition can be analyzed. The optimization problem is subject to a volume constraint, and the design variable is the pseudo density of each element.
