On the Use of Complex Input Power in Topology Optimization of One-Material Vibrating Structures for Obtaining Displacement Anti-resonances Close to Frequencies of Interest

Authors present a topology optimization procedure for steady-state forced vibration problems where a weighted sum between active input power and static compliance is used to obtain anti-resonances of displacement at load points in vibrating structures, at frequencies close to those of interest. The reactive input power, converted to a relation between kinetic energy and potential energy, helps to improve the procedure. Several examples are presented to illustrate the potential of the proposed method.
