The invention discloses a semi-active air pressure
inerter-hydraulic damping combined type anti-galloping
energy consumption device which comprises an outer cylinder, an inner cylinder arranged in the outer cylinder and spacer bushes fixedly installed at the two ends in the inner cylinder, the spacer bushes divide the inner cylinder into a functional cavity and a middle cavity, and the functional cavity and the middle cavity are filled with compressed gas; a first baffle is arranged on one side of the first baffle, a second baffle is arranged on the other side of the first baffle, a flow blocking cavity is formed between the first baffle and the second baffle and filled with flow blocking liquid, a plurality of impellers are arranged between the first baffle and the second baffle, a second
piston is arranged on the other side of the first baffle, a plurality of ball nuts are arranged on the second
piston, and the second
piston, the ball nuts and the rotating rod form a
ball screw pair structure. Through combination of the air pressure
inerter and the liquid damping, semi-
active control is realized, and conductor galloping is efficiently inhibited.
Compressed air circulation gaps in the functional cavity and the middle cavity are communicated with each other, the effect of an
inerter damper is achieved, the weight of the whole device is greatly reduced, the design is reasonable, installation is convenient, and the effect is obvious.
