Technical field
The utility model relates to a kind of connected system of viscous damper, and is a kind of for shockproof viscous damper connected system specifically.
Background technology
In recent years, adopt damper to come earthquake energy, reduce structural response, become one of important means of structural seismic response control technology, the application of damper in building structure, optimal design to damper is the direction of many researcher's researchs for many years always, therefore produce many optimization methods, for example adopted dissimilar dampers such as diagonal angle connected mode and herringbone connected mode.When the sidesway vibration occurs in structure under geological process, the damper diagonal brace that the diagonal angle connects elongates or shortens and forces damper to produce stretching or compression, thereby produce the oblique damping force reverse with displacement structure, herringbone supports the horizontal damping power reverse with displacement structure that then directly produces, and by the herringbone support power is reached this layer lower corner.Under earthquake and wind action, all be to drive system's generation open and close movement by structure generation relative storey displacement, make the damper two ends that relative displacement occur, thereby produce the damping force effect structurally.And then the damping ratio of increase structure, play the effect of energy-eliminating shock-absorbing.Adopt traditional connected mode as the diagonal angle connect, herringbone connects viscous damper calculates under earthquake conditions and only have 20～40mm the range, and generally when ordering damper, the design of producer stroke commonly used is generally 100mm, damper is not fully utilized, this will cause waste, is necessary so adopt the Novel transmission amplifying device that the damper installation form is set.
The utility model content
Technical problem to be solved in the utility model provide a kind of can be in identical vibration damping situation, the stroke of damper is taken full advantage of, can increase simultaneously damper output damping force, thereby increase the viscous damper connected system more than the utilization ratio to 2 times of damper.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of connected system of shockproof viscous damper, comprise lock set linkage and viscous damper, described lock set linkage comprises the first support arm and the second support arm, an end of described the first support arm be connected an end of support arm and connect by the first movable axis axle; Described viscous damper is connected with described the first movable axis.
The beneficial effects of the utility model are: because the price of damper is relevant with damping force and number, therefore in the identical situation of effectiveness in vibration suppression, use the technical program to amplify the damping force of damper output, increased and amplified damper to the action effect of vibration-proof structure; The number of the damper in the practical application can be reduced also that the stroke of damper is fully used, and can save the cost of energy-eliminating shock-absorbing structure.It is as follows to the principle of the damping force of vibration damping agent structure to increase damper about the utility model: use u
DRepresent respectively the relative displacement at damper two ends and the relative storey displacement of its place floor with u, both generally have following relation

It is very large that the damping force F of this explanation damper is subjected to the impact of displacement amplification coefficient f, the lock set connected mode the technical solution of the utility model that employing has enlarging function may obtain larger amplification coefficient than the chevron shaped connection of diagonal sum, thereby can amplify damper to the output damping force of vibration-proof structure.
Further, described viscous damper places the square position of the first support arm.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described lock set linkage also comprises the 3rd support arm and the 4th support arm, an end of described the 3rd support arm be connected the 4th support arm one end and connect by the second movable axis axle; Described viscous damper one end is connected with described the first movable axis, and this viscous damper other end is connected with described the second movable axis.
Adopt the beneficial effect of above-mentioned further scheme to be: in can structure for amplifying viscous damper to the output damping force of shock-damping structure, thereby save the cost of energy-eliminating shock-absorbing structure.
