Problems solved by technology

For example, most dampers have a single mechanism of action and limited vibration reduction capabilities; in addition, some damping devices also have negative effects during use, such as particle damping often lags in response and generates noise, and the additional damping provided by tuned liquid damping is relatively small, etc.

Embodiment 1

[0029] Example 1: See figure 1 , figure 2 , image 3 It is a schematic diagram of views in various directions of the overall structure of the test device of the present invention.

[0030] Container 1 is a cuboid, containing all energy-consuming substances. The movable particle system 2 consists of one or more solid particles 6 made of one or more materials, a bearing rod 7 and a fixed plate 8 . The fixed particle system 3 consists of one or more solid particles 6 of one or more materials and bearing rods 7 . Viscous liquid 4 consists of one or more stable liquids that can be layered or mixed. Its physical properties require heat resistance, non-volatile, non-flammable, stable chemical properties, and the viscosity coefficient depends on the energy dissipation capacity required by the controlled structure. If it is mixed with multiple liquids, it is required that no excessive chemical reaction occurs, preferably no chemical reaction occurs, and it has no corrosive effec...

Abstract

The invention relates to a mixed energy dissipation and vibration reduction damping device with a more perfect energy consumption effect. The device comprises a container, particle systems and viscous liquid and a spring system, wherein the particle systems consist of solid particles, bearing rods and fixing plates. The device integrates the advantages of a particle damper and a tuning liquid damper; when the damping device moves, liquid sloshes to consume energy; holes among the particles improve sloshing energy consumption capacity of the liquid; at the same time, the liquid sloshes to drive the movable particle systems to move; and the movable particle systems impact the fixed particle system on the inner side to consume the energy during reciprocating motion. Due to various mixed energy consumption mechanisms such as the liquid phase friction energy consumption and solid phase collision and friction energy consumption, the device has a greater advantage compared with the traditional vibration reduction damper with a single energy consumption principle.

Description

technical field [0001] The invention belongs to the technical field of energy dissipation and vibration reduction, and relates to a hybrid energy dissipation and vibration reduction damping device. Background technique [0002] With the development of science and technology, structural vibration control devices have become an indispensable structural device for vibration reduction of buildings and structures. The so-called structural vibration reduction control is to install additional control devices on the structure, and the additional devices and the structure itself can jointly resist the dynamic effects of earthquakes and wind vibrations, thereby reducing the dynamic response of the structure to meet the structural safety, usability and comfort. Sexual functional requirements. According to different control mechanisms, structural vibration control can be divided into passive control, active control, hybrid control and semi-active control. At present, passive control ...
