Abstract

The utility model relates to an energy dissipation control apparatus for engineering structures. A tuned mass damping device without guide rails comprises a mass block and a transmission assembly, wherein springs and a viscous damper are arranged at one side of the mass block; the transmission assembly comprises a sliding sleeve and a fixed rod, wherein one end of the sliding sleeve is fixedly connected with the mass block while the other end of the sliding sleeve is sleeved on the fixed rod, and the fixed rod can stretch along the sliding sleeve; the springs are disposed in the sliding sleeves, one end of the spring is fixedly connected with one end of the sliding sleeve away from the fixing rod, and the other end of the spring presses against the fixing rod. With adoption of the abovementioned structure, the transmission assemblies of the slide sleeve structure can be used for limiting the moving direction of the mass block, such that no guide rails for limiting the moving direction of the conventional tuned mass damping devices are additional needed, thereby making the tuned mass damping device be convenient to assemble and low in failure rate.

Description

No guided way formula tuning quality damping unit
Technical field
The utility model relates to technical field of civil engineering, is specifically related to engineering structures energy-dissipating and shock-absorbing control device.
Background technology
In recent years, stride greatly with high building structure more and more.In order to meet the architectural aesthetic requirement, these are striden greatly, and the shared ratio of flat facade irregular structure gets more and more in the high-level structure.How to improve the safety of these irregular structure opposing earthquakes and discharge the temperature deformation that these structures produce in daily use, the various countries scholar has carried out a lot of theory and technology researchs to this.
Wherein, cushion technique is applied to all kinds of newly-built, reorganization and expansion, stabilization works just more and more as mature and reliable, the effective technology that a kind ofly can improve structural seismic performance, reduce seismic hazard.Tuned mass damper (TMD) is one of passive control device in the engineering structures vibrations control.The control principle of the structural dynamic of TMD reaction be with the natural frequency of TMD system be tuned on the main structure natural frequency, thereby can bring into play the maximum absorbing power consumption effect of TMD absorbing.But conventional TMD needs guided way is installed when installing and using, so that the mass of TMD moves the installation process complexity by the direction of appointment.
The utility model content
The purpose of this utility model is, provides a kind of no guided way formula tuning quality damping unit, to address the above problem.
The technical problem that the utility model solves can realize by the following technical solutions:
No guided way formula tuning quality damping unit comprises mass, and a side of described mass is provided with spring, viscous damper, it is characterized in that, also comprises the drive disk assembly of a tube-in-tube structure, and described drive disk assembly comprises a sliding sleeve, a fixed bar,
The fixedly connected described mass of described sliding sleeve one end, the other end is enclosed within on the described fixed bar, and described fixed bar can be flexible along described sliding sleeve;
Described spring is positioned at described sliding sleeve, and the fixedly connected described sliding sleeve of an end is away from an end of fixed bar, and the other end props up described fixed bar.After the utility model adopts this structure, the drive disk assembly of tube-in-tube structure can limit the direction of motion of mass, than the tuning quality damping unit of routine, when settling, need not to establish in addition the guided way for the direction of motion that limits the tuning quality damping unit, easy for installation, fault rate is low.
Described spring has two, be positioned at the both sides of described mass, described drive disk assembly has two covers, is enclosed within respectively on the spring, no guided way formula tuning quality damping unit also comprises a gripper shoe, and the described drive disk assembly of two covers is fixed on the described gripper shoe away from an end of described mass.
Described viscous damper overlaps between the drive disk assemblies the fixedly connected described mass of described viscous damper one end, the fixedly connected described gripper shoe of the other end two.
Described mass is a square mass that is square, and all is provided with two springs on each face of described square mass.
