SYSTEM IDENTIFICATION AND VIBRATION ANALYSIS OF ROTATING BEAM WITH LATTICE STRUCTURES

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 by using FDM 3D printer. Lattice-based generative design program nTopology was used for the design of the beams. Three types of lattice structure such as triangular, hexagonal, and square rotated were used. The experiments were carried out using a setup that includes a servo system and a wireless accelerometer. It has been seen that the obtained models successfully represent the vibration behavior of the rotating beams. The success of the obtained vibration models of the rotating beams were compared and discussed using tables and figures.
