Otimização topológica de absorvedores dinâmicos de vibrações sujeito a vibração livre e forçada

Abstract

The aim of this work is to propose a methodology of application of the FEM and topology optimization technique as tools of analysis and optimal design of mechanical systems subject to natural and forced vibrations in order to reach the optimal geometry of a dynamic absorbing of vibrations. It presents the mathematical reasoning and develop a program in Matlab® that implements the topology optimization technique will be employed to generate the optimal material distribution ( layout ) continuous mechanical systems without external excitation and subject to harmonic forces with preset frequency.
