طراحی و تحلیل ساختار نوین فراماده سلولی مکعبی سه‌بعدی به منظور کاهش ارتعاشات

Vibration reduction has always been one of the fundamental challenges in various industries, leading to increased attention toward the development of advanced engineering materials and the design of novel metamaterials with special structures. In this study, two new three-dimensional cubic metamaterials are introduced and investigated with the aim of improving vibration attenuation performance and expanding the frequency bandgap. To analyze the dynamic behavior of these structures, numerical modeling based on the finite element analysis method was performed using simulation software. In this simulation, the frequency response of the metamaterials was examined, and the obtained results were compared with those of similar cellular structures reported in previous studies. The results indicate that the proposed metamaterials create a wider and more effective bandgap and exhibit better performance in vibration intensity reduction compared to existing samples. Overall, the findings of this research demonstrate that the proposed lattice structures can serve as effective and reliable candidates for designing multifunctional materials with high efficiency in mitigating mechanical disturbances and controlling vibrations.
