Abstract :Today, lattice-structured materials are used in many engineering applications. Research and applications including lattice structures focused on obtaining lightweight components with the optimal distribution. In literature, studies on obtaining vibration models of the beams with lattice structures are limited. In this study, vibration models of rotating beams with lattice structure were obtained by using system identification methods. Beams used in the experimental phase of this study were produced using FDM 3D printer. Three types of lattice structure such as triangular, hexagonal, and square rotated were used. Lattice-based generative design program nTopology was used for the design of the beams. The experiments were carried out using a setup that includes a servo system and a wireless accelerometer. It was proved that the obtained models successfully represent the vibration behavior of the rotating beams. The success of the vibration models of the rotating beams was compared and discussed using tables and figures.
