مطالعه‌پارامتری کنترل ارتعاشات در ساختار مشبک الهام‌گرفته از برگ گل

In this paper, a lattice structure inspired by nature is considered and its vibration behavior is investigated. In the first step, dispersion diagrams are first performed in the frequency band of 0 to 5000 and a numerical study is also performed, and it is found that more than 50% of frequency isolation is created in the structure up to a frequency of 5 kHz. Optimization and analysis of lattice structures and metamaterials with the aim of vibration isolation and control are investigated. Next, a parametric study is performed on a structure with thicknesses of 1.25, 1.5, and 1.75 mm, which shows that changing the thickness causes a change in the total frequency gap, such that the smaller the thickness, the greater the total frequency gap is created in the structure. Recent research innovations emphasize the use of geometric iteration, structural parametric changes, additive resonators, and advanced numerical formulations that improve the efficiency of structures in removing and reducing vibration energy without increasing weight and saving computational time. Finally, the prospects for industrial use of these structures for vibration isolation, noise reduction, lightweight acoustic instruments, and ultra-high-definition acoustic lenses are presented, and future directions in the development of metamaterials and novel engineering structures are outlined.
