A Novel Cylindrical Mechanical Metastructure for Drone Vibration Isolation

Abstract

Drone technologies are widely used for various purposes in many fields. However, the onboard imaging platform is severely compromised by low-frequency vibration during flight, which cannot be suppressed by a general vibration isolation method, leading to poor image quality and failure to fly. In this paper, a novel cylindrical mechanical metastructures (CMMS) vibration isolator was proposed to overcome the drawback of general vibration isolators based on the vibration of the drone imaging platform. By using additive manufacturing, a prototype of the CMMS was fabricated, and experiments were carried out to verify the mechanical properties. In research results, the CMMS isolator has been observed to suppress the full-band frequency vibration of the drone, enabling the imaging platform to operate in a stable environment.
