This study analyzes the natural vibration characteristics of grid beetle elytron plates (GBEPs), a type of laminated plate inspired by the sandwich structure of beetle forewings, under different angles of rotations.
Introduction: Inspired by the forewing structure of Trypoxylus dichotomus, GBEPs have been developed, exhibiting superior mechanical properties over traditional grid plates. This research investigates the effect of layer rotation on the natural vibrational frequencies of GBEPs, a crucial consideration for engineering applications.
Methods: The study utilizes COMSOL Multiphysics 6.1 and the ARPACK solver (https://www.arpack.org/) to analyze the vibrational response of GBEPs. Two identical plates were layered and rotated at angles from 0 to 45 degrees, in 9-degree increments, to examine changes in the first 9 natural frequency modes under various rotational configurations.
Results: Rotational adjustments significantly enhanced the clarity of vibrational modes, with dual-layered GBEPs showing more defined first 9 natural vibration modes compared to non-rotated structures. Rotation induced up to a 12.87% shift in natural frequencies, demonstrating the efficacy of this method in modulating vibrational characteristics.
Conclusions: This investigation highlights the capacity of simple structural modifications in biomimetic designs to achieve desired vibrational performances. Adjusting the orientation of layers in GBEPs allows for flexible vibrational properties, paving the way for their versatile application in different engineering contexts. The study leverages biomimetic principles to offer a novel approach for precise vibrational tuning in material design.
