A hydraulic mem-inerter container device and applications thereof. The hydraulic mem-inerter container device comprises a first cylinder barrel, a first piston, and a spiral passage. The first cylinder barrel is divided by the first piston into a left cavity and a right cavity; and the spiral passage enables the left cavity and the right cavity of the first cylinder barrel to communicate, and the length of the spiral passage changes along with the change of the relative displacement of the first cylinder barrel and the first piston. The cylinder barrel and the piston serve as a first end point and a second end point that are independent and movable correspondingly. When used, the hydraulic mem-inerter container device can be connected to a system to control mechanical force. The hydraulic mem-inerter container device can serve as a regulation and control valve for an inerter and a damper.

Hydraulic mem-inerter container device and applications thereof

A passive skyhook and groundhook damping vibration isolation system and a method for determining parameters thereof, which utilize the anti-resonance of an 'inerter (b1, b2)-spring (k, k)-mass (m, m)' vibration state converting system to convert the resonance of the isolated mass into the resonance of the inerter, thus eliminating the resonance of the isolated mass, is provided. A damper spans and is connected in parallel to the inerter, preventing the damper from spanning and being connected in parallel to the isolated mass. The damper is not required to connect to an inertial reference frame, and the vibration of the isolated mass is suppressed.
