Title:
VIBRATION DAMPING DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/020832
Kind Code:
A1
Abstract:
A vibration damping device, comprising a housing (100), an inertial channel structure (200) and a connecting rod (300), wherein the housing (100) has an accommodation cavity; the inertial channel structure (200) is arranged in the accommodation cavity and partitions same into a first cavity (101) and a second cavity (102), and the inertial channel structure (200) forms an inertial channel (240), which communicates the first cavity (101) with the second cavity (102); the first cavity (101) and the second cavity (102) are filled with a first liquid that flows in the inertial channel (240); the connecting rod (300) has a first end (301) located outside the housing (100) and a second end (302) located in the first cavity (101); and the second end (302) of the connecting rod (300) acts on the inertial channel structure (200) to reduce the area of an inlet (241) of the inertial channel. The vibration damping device can increase a damping force adjustment range, improve a vibration damping effect, and mitigate dynamic hardening when being subjected to high-frequency vibration energy. Further provided is a vibration damping control method.
