AI Technical Summary
Technical Problem
In finite-length periodic structures, unintended wave reflection occurs at the edges where periodicity is lost, reducing the vibration suppression effect.
Method used
A vibration absorption module with a periodic structure sandwiched between two bases, featuring extension branches at the side edges that are free ends, reducing unwanted reflections and improving the vibration suppression effect.
Benefits of technology
The configuration suppresses unintended wave reflections at the edges, enhancing the vibration suppression performance even in structures with limited periods, allowing for a higher suppression effect and potential miniaturization.

Abstract
To provide a technology that can improve the vibration suppression effect. [Solution] A vibration absorbing module is provided, which includes a periodic structure 1 used sandwiched between two bases, a first base and a second base, which are two bases arranged opposite each other. The periodic structure has a configuration in which a plurality of unit cells are arranged periodically, and has a first connecting edge 110 connected to the first base, a second connecting edge 120 connected to the second base, and a side edge that is not connected to the two bases and is oriented in a direction perpendicular to the first direction from the first connecting edge to the second connecting edge. Extension branches are formed on the side edges, which extend outward from the grid points of the periodic structure, and the end opposite to the grid points is a free end.
