摘要：
Mechanical vibrations have been a recurring problem in manufacturing industries, so, its control and isolation are a focus of much research. Metamaterials are a new concept about artificial materials with stunned properties. It means that the material's cellular architecture is designed to improve its mechanical properties, including damping capability. This work proposes a novel metamaterial focus on improving its damping capability. Its cellular architecture is based on a structure to support load and resonators to dissipate vibration energy. The resonators are designed and studied around a specific range of frequencies by a numerical model. Physical models are fabricated by additive manufacture and tested to determine the transmissibility coefficient. The results of experimental tests are reported, and those demonstrate that the damping capability is enhanced by de metamaterial proposed.
