s2-2, constant adjustment L, r0、r1: increase r0Decrease r1Until the performance curve S-gamma curve of the viscous damping wall can envelop the S-gamma curveDesign ofDesigning curves, i.e. for the same S, gamma>γDesign of。
The invention has the advantages that:
first, one of the concepts underlying the present application: the design of a viscous damping device is provided, and the viscous damping device has the following advantages: one is that the shear plate axis of rotation may be less high from the upper beam.
The prior art is as follows: CN110777957A, when the relative displacement between the upper beam and the lower beam is large, the radius of the gear 3 needs to be made large. At this time, the height of the shear plate is necessarily limited.
For example: compared with solution four, the shear plate of the prior art is 2.5m, and the shear plate of solution four is 2.7m, i.e. the shear plate height of the present application/shear plate height of the prior art is 1.12 times (the linear velocity of the end of the present application is also 1.1.2 times the linear velocity of the end of the prior art).
Secondly, if the prior art CN110777957A needs to maintain the same height of the shear plate as the present application, the gear radius must be made small, which in turn affects the energy consumption protection range (i.e. Smax must be affected).
The application is not affected by the above, and the gear 4-1 is a full-tooth-line section.
Second, the present application adopts an S- γ curve as a method for evaluating performance, S being a relative displacement between the first structure and the second structure, and the relative displacement increases from 0 to S.
When the relative displacement between the first structure and the second structure is 0, γ is 0.
For the same S, a larger γ indicates a higher angular velocity of the shear plate and a higher damping effect, i.e., a velocity amplified.
As can be seen from fig. 5 and 6, the angular velocity of the solution of the present application is not necessarily faster than that of the CN110777957A of the prior art. As can be seen from FIGS. 5-6, the present application is in an initial state: when the cylindrical rod is arranged above the central rotating shaft of the gear, the effect is greatly improved(ii) a And by adjusting L, r0、r1The size of the three can greatly adjust the effect of the damping device of the application.
That is, the scheme of the present application has conditions, and can further improve the linear velocity of the steel plate of the viscous damping device on the basis of CN 110777957A.
Thirdly, the present application presents a performance evaluation method for determining the aforementioned viscous damper (which is another application because of the lack of unity with claim 1), that is, quantitatively evaluating the performance of the aforementioned viscous damper by studying the S- γ curve.
Specifically, the following formula is adopted:

wherein the content of the first and second substances,
Figure BDA0002750195790000042
indicating taking an integer.
Fourth, the present application presents a design method for determining the aforementioned viscous damper, the designer specifying the desired S- γDesign ofDesign curve by adjusting L, r0、r1Three parameters are used for calculating an S-gamma curve which can envelop the S-gammaDesign ofDesign curve, i.e. required L, r0、r1(e.g., as shown in FIG. 6, CN110777957A is S- γ given by the designerDesign ofDesign curve, by comparison, the parameters of scheme four are required).
Fifth, the design of this application is applicable to the prefabricated frame-type factory building structure of individual layer very much.

holes are formed in side plates on two sides of the viscous box, two sides of a hinged shaft 5-3 of the shearing device penetrate through the holes formed in the side plates on two sides of the viscous box, and acting force borne by the hinged shaft is transmitted to the side plates of the viscous box;

The following are interrelated: the central line of the gear central rotating shaft 4-3 and the central line 5-3 of the shearing device articulated shaft are positioned in the same vertical plane;
the distance between the center line of the gear center rotating shaft 4-3 and the center line of the shearing device articulated shaft 5-3 is L, and the distance between the center line of the cylindrical rod 4-2 and the center line of the gear center rotating shaft 4-3 is r0(ii) a The radius of the gear 4-1 is r1；

Figure BDA0002750195790000061
when the relative speed of the upper beam 1 and the lower beam 2 is V, the speed V of the shearing plate with the length of x from the articulated shaft 5-3 of the shearing device is VxNamely:

Figure BDA0002750195790000064
Comprises the following steps:
Figure BDA0002750195790000065
comparing the solution of the present application with the prior art CN110777957A,
Figure BDA0002750195790000066
FIG. 4 shows the difference L/r0In the case of the above-described situation,
Figure BDA0002750195790000067
the numerical value of (A) is shown in FIG. 4, L/r0The smaller (but it cannot be 1.0 or less), VxThe larger.
The mature of the prior art and the scheme of the application cannot be clearly analyzed by the formula (5). Thus, another way of analysis is to illustrate:
for prior art CN 110777957A: when the relative displacement of the upper beam and the lower beam is S, the distance between the upper shearing plate and the central shaft of the gear is x, and the distance is as follows:
Figure BDA0002750195790000071
for the application, in an initial state, the central line of a hinged shaft 5-3 of the shearing device, the central line of a gear central rotating shaft 4-3 and the central line of a cylindrical rod 4-2 are positioned on the same vertical plane, and the cylindrical rod 4-2 is positioned below the gear central rotating shaft 4-3; for the relative displacement of the upper beam and the lower beam as S, the angle of the cylindrical rod 4-2 rotating around the center of the gear central rotating shaft 4-3 is theta:
the rotating angle gamma of the shear plate and the distance S between the shear plate and the central shaft of the gear, which is the distance traveled by xXRespectively as follows:
Figure BDA0002750195790000072
wherein r is1The radius of the gear 4-1 is shown.
Specifically, an example is taken as an example to illustrate:
when CN110777957A is applied to frame structure in prior art, the height between upper beam and lower beam is 3m, Smax0.125m, 22.5 ° r' ═ 1/pi ═ 0.32 m; the shear plate height was 2.4 m.
Correspondingly, the application proposes three schemes: it has the following common features: the height between the upper beam flange and the lower beam is 3m, and the distance between the upper beam web and the lower beam is 2.4 m; other differences are shown in the following table
Parameter(s) Scheme one Scheme two Scheme three
r0(m) 0.25 0.25 0.25
r1(m) 0.1 0.2 0.3
L(m) 0.6 0.7 0.8
Height of shear plate (m) 2.7 2.7 2.7
The solution of the present application has the advantage that the height of the shear plate is increased (CN 110777957A in the prior art needs to satisfy the requirement that the radius of the gear is larger, the height of the central axis of the gear from the upper beam is larger, thus resulting in a lower height of the bottom of the shear plate from the central axis of the gear; whereas the position of the articulated shaft 5-3 of the shearing device is not limited, thus the height of the shear plate is higher).
However, it is unexpected that the solution of the present application is not superior compared to the prior art. That is, when the upper beam-lower beam relative displacement is S, the rotation angle of the CN110777957A solution is greater than the rotation angles of the first, second, and third solutions (correspondingly, the rotation path of the CN110777957A is greater than the rotation path of the first, second, and third solutions for a point of the radius x).
In this regard, the inventors found that: the effect of the scheme of the application can be greatly improved by adjusting the initial state. In an initial state, the central line of a hinged shaft 5-3 of the shearing device, the central line of a gear central rotating shaft 4-3 and the central line of a cylindrical rod 4-2 are positioned on the same vertical plane, and the cylindrical rod 4-2 is positioned above the gear central rotating shaft 4-3;
for the relative displacement of the upper beam and the lower beam as S, the angle of the cylindrical rod 4-2 rotating around the center of the gear central rotating shaft 4-3 is theta:
parameter(s) Scheme four Scheme five Scheme six
r0(m) 0.25 0.25 0.25
r1(m) 0.1 0.2 0.3
L(m) 0.6 0.7 0.8
Height of shear plate (m) 2.7 2.7 2.7
Namely, the parameters of the scheme four, the scheme five and the scheme six are the same as those of the scheme one, the scheme two and the scheme three, and the difference is only that the initial state adopts: the position of the cylindrical rod 4-2 is different.
Comparing fig. 5 and fig. 6, it can be seen that the performance effect of the scheme four, the scheme five, and the scheme six is greatly improved compared with the scheme one, the scheme two, and the scheme three, but only the effect of the scheme four is greatly superior to that of CN 110777957A.

the distance between the center line of the gear center rotating shaft 4-3 and the center line of the shearing device articulated shaft 5-3 is L, and the distance between the center line of the cylindrical rod 4-2 and the center line of the gear center rotating shaft 4-3 is r0(ii) a The radius of the gear 4-1 is r1；
