Machine Learning-Driven Design Optimization of Buckling-Induced Quasi-Zero Stiffness Metastructures for Low-Frequency Vibration Isolation

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(14), P. 17965 - 17972

Published: March 27, 2024

Metastructures, artificial arrangements of micro/macrostructures, possess unique properties and are significant interest in aerospace, stealth technology, various other applications. Recent studies have focused on quasi-zero stiffness metastructures, providing an outstanding vibration isolation capability. However, existing methods constrained to low preloads lack the consideration structural analysis, despite their intended use practical structures. This study introduces metastructures with characteristics under high by inducing local buckling. An optimization framework combining deep reinforcement learning finite-element analysis is employed derive optimal model that considers both safety characteristics. To validate results, fabricated via 3D printing, compression experiments conducted. The exhibit a target preload along reduction performance, even low-frequency range.
