Effects of Viscous Fluid Damper production technology, performance indicator is reliable and stable, and has been applied in a large amount of engineerings.And stroke compared with
Big viscous damper, develops difficulty bigger, and dosage is less, therefore super large-scale damper develops, and is difficult to always
Break through.
The test capability of testing stand equally constrains the development and exploitation of the damper of big stroke, and according to investigations, domestic CMA recognizes
The laboratory of card, its test bed testing ability are：350 tons, range 800mm of peak load, test specimen maximum length 6m, maximum
Speed 1m/s.These parameters are all single index theoretical maximum abilities, and practical capacity can have a greatly reduced quality, such as 300 ton hours of contributing, most
Big stroke only has 500mm.Such testing stand disclosure satisfy that common buildings and the testing requirement of bridge damper.It is high to some
Intensity area isolation structure and the very big bridge structure of wind load, the displacement stroke of damper cause often beyond actual tests ability
Damper can not be detected directly, and some carries out indirectly testing using reduced scale damper, or only according to the maximum of testing stand
Ability is detected, and properties of product reliability is difficult to objective judgement.
Utility model content
The technical problems to be solved in the utility model is in view of the above shortcomings of the prior art, and to provide a kind of big stroke and stick
Stagnant fluid damper, the big viscid fluid damper of stroke is by the way that small stroke damper is in series, after making series connection
The maximum travel limit of big damper increases between 600 ~ 1200mm, and can be configured as needed, and it is simple in structure, grind
It is made low.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of viscid fluid damper of big stroke, including small damper one, small damper two and main piston rod, small damper
One is identical with the maximum output of small damper two, and range is respectively less than 600mm.
Small damper one and small damper two are coaxially arranged in series, wherein, the master cylinder and small damper two of small damper one
Master cylinder be oppositely arranged, after the piston rod of small damper one and the piston rod of small damper two are fixedly and coaxially connected, form main work
Stopper rod.
The piston rod of small damper one and the piston rod of small damper two are wholely set.
The piston rod of small damper one is connected with the piston rod of small damper two by jointing.
Jointing is one kind in welding, ring flange connection and screwed connection.
Small damper one is identical with the specifications and models of small damper two.
The utility model with the above structure, the small damper of small stroke is connected by physics, is assembled into big stroke
Viscid fluid damper, the maximum travel limit that the utility model assembles the viscid fluid damper of big stroke to be formed can be
It is adjusted between 600 ~ 1200mm.Since the small damper of small stroke is widely used, its performance parameter is reliable and stable.Series connection and
Into damper, only series connection physically, its performance can directly calculate by small damper.
In addition, the application, by way of piston rod is fixedly connected, concentricity is high, and can be synchronized with the movement, Stroke Control
It is more accurate, reliable.
In addition, the mechanical property such as output, the stroke of the application by testing small damper, can directly extrapolate big damping
The mechanical properties such as the output of device, stroke.Equivalent to the covert dilatation of testing stand stroke capability, it is not necessary to spend a huge sum of money for this
Reforming test platform.
Tested compared to reduced scale and only accomplish the test method of testing stand range, the utility model proposes directly test
Small damper, the detection mode directly calculated according still further to series relationship, its detection means is more direct, and conclusion (of pressure testing) more may be used
Lean on.

Embodiment
The utility model is described in further detail with specific better embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Figure 1, a kind of viscid fluid damper of big stroke, including small damper 1, small damper 27 and main work
Stopper rod 2, small damper one is identical with the maximum output of small damper two, and range is respectively less than 600mm.
Small damper one and small damper two are coaxially arranged in series, wherein, the master cylinder and small damper two of small damper one
Master cylinder be oppositely arranged, after the piston rod of small damper one and the piston rod of small damper two are fixedly and coaxially connected, form main work
Stopper rod.
The piston rod of small damper one is by 5 phase of jointing with the mode that is fixedly connected of the piston rod of small damper two
Connection, jointing are one kind in welding, ring flange connection and screwed connection etc..
In the application, the specifications and models of small damper one and small damper two are preferably identical, namely maximum output, stroke,
The mechanical properties such as frequency are identical, and error is within specification allowed band.
When relative displacement occurs for the viscid fluid damper both ends of big stroke, two small dampers do same stretching respectively
Or compression, main piston rod movement, drives the energy consumption of damping hole jet stream, due to same-phase relation, so the viscid fluid damping of big stroke
With small damper, stroke and speed just expand to be twice the output of device.Since the Development Techniques of small damper are mature and stable, pass through string
Join the big damper of composition of relations, as long as switching performance is reliable and stable, the mechanical index such as its output, stroke is equally reliable.So
It can be realized as equally producing the viscid fluid damper of big stroke of the application using the production technology of small damper.
When the big viscid fluid damper of stroke detects, two small dampers can be first detected, method and requirement are according to existing
Row inspection criterion requires to perform, and the Testing index of the viscid fluid damper of big stroke is directly obtained according to tandem principle.It is if small
The output of damper, stroke, frequency etc. are in the test scope of testing stand, it is possible to by output, the position of detecting small damper
Divide a word with a hyphen at the end of a line the parameters such as journey, frequency, the output of big damper is identical with small damper, and stroke, speed are 2 times of small damper.
Certainly as replacing, the specifications and models of small damper one and small damper two can be different, due to current small damping
The range of device is within 600mm, therefore the application assembles the range model for the viscid fluid damper of big stroke to be formed
Enclosing can be adjusted between 600 ~ 1200mm.Since the small damper of small stroke is widely used, its performance parameter is reliable and stable.
The damper being in series, only series connection physically, its performance can directly be calculated by small damper.
