Lead, and one group of butterfly spring being enclosed on lead, comparatively speaking, butterfly spring are stiffness factor maximums in spring
One kind, but still poor compared to mild steel damper, therefore, the size of its vertical direction is bigger than normal, easy unstability, therefore,
It is had in the periphery of butterfly spring and sets some c-type mild steel dampers, and c-type mild steel damper is not only further increased
The elasticity of bridge pad, and butterfly spring segmental stability can be made more preferable.But c-type structure belongs to a kind of bow-shaped structural, no
It is evitable to increase the volume of bow direction, and generally speaking, mild steel damper cooperates with produced structure with butterfly spring
It is partially complicated.

Structure, the mild metal damper 3 shown in figure is provided with connection between a kind of double ring body structurcs with common axis line, two ring bodies
Part, such as the spoke 33 shown in figure, it is mild steel matter on the whole, and when externally-located ring body, some direction is squeezed
When, it can be deformed, produce damping.
Ring body is that in the range of 360 degree, it deforms the elastic deformation for showing ring body to the response around extruded.Because of outside
Factor is caused after the factor elimination of ring body deformation, and elastically-deformable recovery can reset such bridge pad.
In the structure shown in Fig. 5, mild metal damper 3 has the outer ring body 31 of direct load metamorphism, and for installing
The inner ring body 32 of mild metal damper 3, wherein inner ring body 32 be sleeved on column 5 and with the coaxial line of outer ring body 31 so that its
The response that extruding to periphery is produced is roughly the same.
Due to also there is annexation, the spoke 33 of inner ring body 32 and outer ring body 31 is connected as shown in Figure 5, it is clear that more
Static stiffness close to the outer ring body 31 of spoke 33 is bigger, under the conditions of identical extruding force, and the deformation of generation is just smaller, therefore,
Outer ring body 31 in addition to specific region, is substantially different to the response produced by periphery.
Specific region, the position that for example four spokes 33 are directly connected to, in the ideal situation, it should be understood that be phase
With.
In addition, as further configuration, be rigidly connected between upper bracket plate 1 and column 3,32 sets of column 3 and inner ring body
Dress, the extruding that outer ring body 31 is subject to should derive from the opposite force of lower support plate 2, it is clear that in order to realize damping, then lower support plate
