Abstract Continuum topology optimization considering the vibration response is of great value in the engineering structure
design. The aim of this study is to address the topological design optimization of harmonic excitation structures with
minimum length scale control to facilitate structural manufacturing. A structural topology design based on discrete
variables is proposed to avoid localized vibration modes, gray regions and fuzzy boundaries in harmonic excitation
topology optimization. The topological design model and sensitivity formulation are derived. The requirement of
minimum size control is transformed into a geometric constraint using the discrete variables. Consequently, thin
bars, small holes, and sharp corners, which… More >
