波纹面生物仿生蜂窝结构力学性能

Inspired by the excellent mechanical properties of natural corrugated structures, a novel corrugated square honeycomb (CSH) structure was proposed. The CSH has been successfully prepared using a 3D printer based on fused deposition manufacturing (FDM) technology. A quasi-static compression mechanical analysis was conducted on the CSH using a universal material testing machine, and its load curve characteristics and various compression mechanical performance indicators were evaluated. The research results indicate that the introduction of the corrugated design significantly enhances the mechanical properties of the square honeycomb. By reasonably adjusting the values and combinations of the corrugated surface\'s radius (R), wall thickness (T), and outer contour edge length (L), an CSH design can be achieved with higher energy absorption capacity, higher specific energy absorption and lower initial peak force. This study not only unveils the vast potential of biomimetic corrugated design in optimizing the mechanical properties of honeycomb structural materials but also offers valuable references for the design and application of new structural materials.
