Description
Technical field
It is to be related to a kind of full assembled tuned mass damper, TMD specifically the present invention relates to a kind of damper.
Background technology
Tuned mass damper, TMD is one kind of the passive vibration damping control system of structure, and it is by main structure and is attached in main structure
Minor structure composition, the minor structure include quality system, support system（Spring and damper）, and typically hang or be supported on knot
On structure.
The working mechanism of tuned mass damper, TMD is " with dynamic braking " to be controlled or weakened with a motion for mass
The motion of another mass, by motivation of adjustment characteristic, makes its natural frequency of vibration try one's best close to the fundamental frequency or sharp of main structure
Frequency is encouraged, when main structure is subject to extraneous load incentive action and vibrates, tuned mass damper, TMD will produce one with main knot
The opposite inertia force of structure direction of vibration is acted in main structure, so that the dynamic respons of main structure are decayed and are controlled.
There are two large problems in existing tuned mass damper, TMD.One is the making of mass, due to there is some frequency modulation mass to damp
Device uses steel reinforced concrete block as mass, therefore fabrication cycle is long and small product size is big, is limited by installing space, and in addition
Although steel plate, as mass, need to be connected into an entirety, therefore apply by some using certain amount steel plate using welding
Work operation is more, processing cost is higher, and due to can only the welding on the outside of steel plate, therefore also have certain shadow to its presentation quality
Ring；Although two is that current existing tuned mass damper, TMD can adjust, execute-in-place is relatively difficult, such as some people
In row overline bridge engineering, tuned mass damper, TMD is that field adjustable is carried out in the steel box-girder of overline bridge in Cheng Qiaohou, works as steel box-girder
When height is smaller, scene is by increasing（Reduce）Spring increases mass and is almost inoperable carrying out frequency modulation.
Therefore, based on above-mentioned problem, it is necessary to design a kind of improved full assembled tuned mass damper, TMD, not only processing side
Just, fabrication cycle is short, small volume and cost is relatively low, while space is small needed for field adjustable, frequency modulation is easy to operate, not by live empty
Between limitation.
The content of the invention
It is an object of the invention to solve above-mentioned problem, a kind of improved full assembled tuned mass damper, TMD is proposed, should
Damper is not only easy to process, fabrication cycle is short, small volume and cost is relatively low, while space is small needed for field adjustable, frequency modulation behaviour
Facilitate, do not limited by site space.

There is gathering sill, and be slidably connected by gathering sill and fixed tubular pillar guiding between the bottom panel and top panel.
Overall mass connects regulation mass by connecting cylinder, leads between regulation mass and connection cylinder
Cross threaded connection.
Top board need to be more than overall matter by four tubular pillars and lower raft bolt connection, top board with the spacing of mass
Gauge block range in normal operation.
Spigot surface is contacted between cylindrical column and the mass of entirety and is provided with non-cohesive material layer.
Mass is made up of perforate circular steel plate, and circular steel plate is provided centrally with the different circular hole of some diameters, and circular hole is straight
Footpath is provided with total length internal thread in the circular hole more than damping element and the diameter of Vertical Spring along thickness of slab direction, and by total length
Screw thread connects into a mass entirety with cylinder is connected, and mass inside is provided with a number of vertical circular hole, circular hole simultaneously
Interior arrangement Vertical Spring, mass is supported on Vertical Spring.
Connection outside diameter of cylinder Circularhole diameter corresponding with mass inside is identical, and total length external screw thread is provided with along external cylindrical surface,
Total length external screw thread is connected with the total length screw-internal thread fit of the circular steel plate center hole of mass, connects the length of cylinder more than whole
The mass gross thickness of body, for connecting regulation mass.
The beneficial effects of the invention are as follows：
1st, the present invention uses full assembled manufacture craft, can use pre-engineered part, therefore easy to process, cycle is short, body
Product is small and cost is relatively low；
