Abstract

This paper modified the Dynamic Antiresonant Vibration Isolator (DAVI) with a flexible lever, reducing weight and/or isolation frequency. An analytical model predicts that a compliant lever design can provide the same isolation frequency as that of a rigid DAVI but with half the auxiliary mass. The analytical model also shows that for the same auxiliary mass, compliant levers can provide lower isolation frequencies compared to DAVIs with rigid levers. The proposed isolator includes monolithic compliant features that are realizable with additive manufacturing, which reduces friction and wearing losses compared to traditional isolators. Two fabricated and tested devices validate the model and demonstrate the improved performance of a flexible design.
