Abstract
Recently, many level set-based topology optimization methods have been proposed. Among them, our previously proposed level set-based topology optimization method has an advantage of eliminating grayscale elements because of incorporating the arbitrary Lagrangian Eulerian method. In this paper, we apply the previously proposed method to a compliant mechanism design problem. Since grayscale elements are completely eliminated, there is no ambiguity of the optimized structure in the engineering sense. This characteristic is very important in compliant mechanism design because compliant mechanisms usually have thin hinge parts. We demonstrate the usefulness of the proposed method using a numerical example.
