Abstract

A design method to enhance both mechanical and vibrational isolation properties of honeycomb meta-material is proposed and verified by a proposed in-folded hexagonal honeycomb meta-material (I-HHM). Based on the traditional hexagonal honeycomb structure (T-HHM), the I-HHM is designed with in-folded bars instead of straight bars and rings at the joints, and metal pins are inserted into the rings. The mechanical and vibrational suppression performance of the I-HHM is analyzed by finite element method and experiment. The results show that compared with the T-HHM, the I-HHM has greater advantages in load-bearing capacity and stiffness, and has wider bandgaps. In addition, according to the concept of assembly, the combination of particle damping and rings can direct vibration energy to the local structure for consumption, which further enhances the vibration reduction and customization capabilities of the I-HHM. The proposed method provides a feasible way for the optimization of meta-materials.

期刊介绍： The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials. The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
