Patent ID: 11815150

Abstract:
A magnetostriction-based vibration suppression apparatus for a steel pipe of a power transmission tower includes a lantern ring, four spoiler cups, and two control boxes; the lantern ring is fixedly sleeved on the steel pipe; mouths of the spoiler cups face outwards, and bottoms thereof are hinged on the lantern ring; the four spoiler cups are squarely distributed; and the two control boxes are symmetrically and fixedly mounted on the lantern ring; the control boxes are arranged as follows: the spoiler cups are arranged in pairs as a group, and each control box is arranged between two spoiler cups; each control box is provided therein with two groups of inerter units corresponding one-to-one to the spoiler cups. The vortex is avoided using a structure such as a spoiler cup, and the vibration kinetic energy of the steel pipe is consumed, thereby achieving an effective vibration reduction effect.
