Compliant mechanism design based on the level set and arbitrary Lagrangian Eulerian methods. (English) Zbl 1274.74254
Summary: This paper deals with continuum-based compliant mechanism design. In topology optimization, filtering techniques are used for the regularization of the design space. In the density design representation, convolution-type filters inherently produce gray transition regions between solids and voids. In order to reduce the gray transition regions, projection schemes have recently been proposed. Binarization, however, still leads to one-node connected hinges in compliant mechanism design. In this paper, we propose a method that incorporates the level set and arbitrary Lagrangian Eulerian methods so that the gray transition regions are completely excluded and one-node connected hinges are not formed.
