Optimal Design the Compliant Bistable Mechanism based on NSGA-II

Abstract

The bistable mechanism has a vital role in precision engineering and robotics with benefits in free friction, no backlash and saves energy. Multi-objective optimization techniques have many applications in design mechanism. NSGA-II is strengthening in quick sorting procedure and elitist methodology. This article introduces an optimization methodology for design compliant bistable mechanisms by employed non dominated sorting genetic algorithm II (NSGA-II). The method predicts the switching forces in forward and backward motion of the bistable mechanism. The program of NSGA-II was executed in Matlab combine with Abaqus to analyze the mechanism. A flowchart of processing is introduced. An example of a bistable mechanism is investigated and results are adopted by applying NSGA-II in order to verify the method.

Design and Simulation the Compliant Linear-Rotary Mechanism with Thermal Actuator

“…The finite element method (FEM) is also employed to analyze the V-shaped beam's angle, which Joshi et al proposed [14]. Simulation with Abaqus software employed in many structure [15]. Baracu et al [16] designed the Chevron type thermal actuators formed on multiple V beams and fabricated by Reactive Ion Etching (RIE) processing.…”
