Title:
VIBRATION ISOLATION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/032003
Kind Code:
A1
Abstract:
Provided is a vibration isolation structure that can reduce vibration that is transmitted from a vibrating section to a vibrated section and comprises: a first beam that has one end thereof connected to the vibrating section, either directly or via a first support section; and a second beam that has one end thereof connected to the vibrated section, either directly or via a second support section and has the other end thereof connected to the other end of the first beam, via a node. In the axial direction of an axis that passes through a first position on the vibrating section and a second position on the vibrated section, the node is positioned on the first position-side or the second position-side, relative to one end of the first beam and one end of the second beam. The rotational displacement of the node excited by translational displacement of the vibrating section and transitional displacement of the node resulting from the translational displacement of the vibrating section, has an anti-resonance that is within a frequency range that is higher than the primary resonance frequency and lower than a secondary resonance frequency of the vibration isolation structure.
