Title:
VIBRATION TRANSMISSION SUPPRESSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/038690
Kind Code:
A1
Abstract:
A vibration transmission suppression device (100) comprises a plurality of unit cells (10a-10f) that are provided between a support target and a base surface, which receives forced displacement, and are connected in series in a vibration transmission direction (400). Each of the plurality of unit cells (10a-10f) has an elongated shape extending in a first direction intersecting with the vibration transmission direction (400) and includes a partition wall (20) that forms a closed cross section (11) and a fluid (30) that is filled in a space enclosed by the partition wall (20). The partition wall (20) has a structure to cause a change in the area of the closed cross section (11) in response to load applied in the vibration transmission direction (400); at least one end section (21) of the both end sections in the first direction is open; and adjacent unit cells (10a-10f) contact each other through the partitions (20).
