Novel tuning inertial rotary damper

Abstract

The invention relates to the technical field of building damping, and discloses a novel tuning inertial rotary damper. The rotary damper comprises a spring part used for axial movement of a transmitting structure and a rotary damping part used for dissipating energy; the spring part and the rotary damping part are connected through a ball screw pair, so that conversion from axial movement to radial movement is achieved, and the movement amplitude is amplified; and a nut connected with the ball screw pair is further connected with an adjustable mass adjusting block. The novel tuning inertial rotary damper has the functions of an energy dissipation type damper and a tuning type damper, and the performance parameters of the damper can be rapidly adjusted by adjusting the overall rigidity of the spring part, the lead of the ball screw pair and the mass of the mass adjusting block.

Description

technical field [0001] The invention relates to the technical field of building shock absorption, in particular to a novel tuned inertial rotation damper. Background technique [0002] As a new type of energy-consuming shock-absorbing device, the damper is widely used in the field of vibration reduction of bridges, high-rise buildings and other engineering structures. Generally, dampers can be divided into liquid viscous energy consumption, metal material buckling energy consumption and material friction loss according to their functions. There are two types of energy-dissipating dampers, which mainly focus on energy dissipation and shock absorption, and tuned dampers, which use the principle of anti-point resonance to improve structural vibration characteristics. With the increasing use of dampers, they often need to be used simultaneously for structural vibration control. Energy-dissipating dampers and tuned dampers are used to meet the design requirements, but generally e...

[0002] As a new type of energy-consuming shock-absorbing device, the damper is widely used in the field of vibration reduction of bridges, high-rise buildings and other engineering structures. Generally, dampers can be divided into liquid viscous energy consumption, metal material buckling energy consumption and material friction loss according to their functions. There are two types of energy-dissipating dampers, which mainly focus on energy dissipation and shock absorption, and tuned dampers, which use the principle of anti-point resonance to improve structural vibration characteristics. With the increasing use of dampers, they often need to be used simultaneously for structural vibration control. Energy-dissipating dampers and tuned dampers are used to meet the design requirements, but generally energy-dissipating dampers can have a good energy-dissipating effect under large displacement deformation, while tuned dampers generally have a small frequency adjustment range, and the overall quality Larger and more expensive to produce
