Numerical study of the vibration control performance of Kelvin foam

Vibration control in microsystems is an important challenge. Because of the space limitation, structures that consume minimal space but provide effective performance need to be identified. In this research, we evaluate the vibration damping performance of Kelvin-cell structures in microsystems using the Finite Element Method. Two types of unit cells are designed based on the tetrakaidecahedron with different geometric parameters. The lattices are composed of the aforementioned unit cells, and the boundary conditions are set according to the actual application scenarios. The results are compared with each other and two types of non-Kelvin-cell structures and show that the faces on Kelvin cells are important for vibration control. This comparative analysis aims to inform the development of space-efficient vibration absorbers for microsystems.
