Abstract
Abstract: Compliant mechanisms are monolithic structures, in which the deformation property is explored as source of its motion. These mechanisms have wide application in devices that involve precision mechanics, such as MEMS actuators. In this work, the topology optimization method (TOM) powered by an integration routine between MATLAB and ANSYS software are implemented to design 3D compliant mechanisms. TOM is a powerful optimization algorithm to distribute material inside a design domain in order to obtain better structural layout to the compliant mechanism. The easy communication between both softwares (MATLAB and ANSYS) provides an efficient alternative to hand hundreds of thousands of design variables and solve large FE equation systems necessary to design 3D mechanical structures. The well-know SIMP (Solid Isotropic Material with Penalization) and the Optimality Criteria method (OC) have been applied respectively as material model and numerical optimization solve for TOM. Some results are shown to illustrate the potential of the implemented algorithm.
