On the other hand, above the ground or lower structure D, below the structure or a part A thereof, a housing 10 capable of accommodating a viscous body 1 having a predetermined viscosity in an enclosed state.
Is being built. The viscous body 1 is housed in the housing 10 in a sealed state without leakage, and two viscous bodies 1 are attached to each of the two rotatable shafts 2 rotatably erected. The disc-shaped rotary disc 3
It is soaked four times for convenience. The upper and lower ends of the rotary shafts 2 are rotatably supported by bearings 11, respectively, and are erected in the vertical direction and arranged side by side in the housing 10 in the horizontal direction. As shown in FIG. 1c, each rotary disc 3 has a left end of the upper rotary disc 3 of the right rotary shaft 2 below the right end of the upper rotary disc 3 of the left rotary shaft 2. The left end of the lower rotary disk 3 of the right rotary shaft 2 overlaps the right end of the lower rotary disk 3 of the one rotary shaft 2 so that they do not interfere with each other.

From the lower end of the displacement transmission rod C, a displacement take-out rod 5 is rotatably extended in the horizontal direction. The displacement take-out rod 5 is penetrated through the housing 10 through a seal member 12 or the like so as to pass between the pinions 4 of the two rotary shafts 2. On both side surfaces of the displacement take-out rod 5, the rack 6 extends over a portion facing the pinion 4 and a portion having a length corresponding to the relative displacement of the supposed structure or a part A thereof or a length several times the length.

Therefore, when a relative displacement occurs in the structure or a part A thereof due to vibration or the like, this relative displacement is transmitted to the displacement extracting rod 5 through the displacement transmitting rod C without delay. Since the transmitted displacement is simply replaced by the displacement in the horizontal direction, the rotary shafts 2 and the rotary discs 3 attached thereto rotate in opposite phases to each other in accordance with the displacement. At this time, a viscous resistance is generated between the entire surface of the rotating rotary disc 3, that is, the contact surface with the viscous body 1 and the viscous body 1, and the viscous resistance attenuates the rotational force of the rotary disc 3. The displacement of the displacement extraction rod 5 is damped by this rotational damping force, and this displacement damping force becomes the vibration damping force of the structure or a part A thereof, that is, the vibration damping force. On the other hand, when a pair of two rotary discs 3 are superposed on each other and rotated in opposite directions as in the present embodiment, the viscous body 1 interposed between the two viscous bodies 1 is caused by its viscoelasticity. The force works to move in the same direction. With respect to the force for moving this part of the viscous body 1, the enclosed viscous body 1 as a whole generates a force that inhibits it due to its own inertial force and viscous resistance, so this inhibiting force causes the rotation of the rotary disc 3. It becomes a damping force, which also becomes the damping force of the structure or a part A thereof. In addition, the viscous body 1 existing between the rotary plate 3 and the fixed portion such as the housing 10 is
A shearing force and an inertial force are generated by the rotary motion of the rotary board 3, which also serves as a vibration damping force. Note that the viscous resistance is generated by the shearing force generated in the viscous body 1 due to the frictional force existing between the rotary disc 3 and the viscous body 1, and the shearing deformation force being absorbed by its own viscosity. It can be understood that energy is absorbed. Therefore, the rotary board 3
The damping force due to energy absorption increases as the total surface area of the disk increases, and at the same time, the shear deformation force increases as the rotational speed of the rotary disc 3 increases, resulting in a large damping force. As a condition for satisfying both, for example, the larger the diameter of the rotary disc 3 is, the larger the damping force becomes. Also, in this case, the rotary board 3
Since the inertial force also contributes to the damping force or energy absorption, it is effective to increase the diameter of the rotary disc 3 also from this.

FIG. 2 shows another embodiment of the damping device of the present invention. A displacement transmitting rod C for transmitting a relative displacement from a structure or a part A thereof, and a displacement extracting rod 5 extending therefrom. The specific structure of is similar to that of the embodiment shown in FIG. In this embodiment, the diameter of the rotary disc 3 is increased in order to increase the damping force as described above, and the number of the rotary discs 3 attached to each rotary shaft 2 is limited to one. On this occasion,
In order to prevent the rotary discs 3 from interfering with the rotary shafts 2, the rotary shafts 2 ahead of the pinion 4 are cut, and the rotary shafts 2 are cantilevered. Then, in order to improve the support rigidity of the rotating shaft 2, two bearings 11 were used at each cantilevered portion.

By increasing the diameter of the rotary platen 3 as described above, the contact surface area of the rotary platen 3 with the viscous body 1 increases and the viscous resistance increases, and at the same time, the rotation of the rotary platen 3, especially on the peripheral surface. The speed is increased, which increases the deformation shear force and consequently the damping force. FIG. 3 shows another embodiment of the damping device of the present invention.
Four rotary shafts 2 are erected in a staggered manner with respect to the disposition direction of the displacement take-out rods 5, and two rotary discs 3 are attached to each rotary shaft 2 in a staggered manner. It is arranged so that it overlaps with.

With this structure, it is possible to effectively convert the rotational movements of the rotary shaft 2 and the rotary disc 3 from a certain relative displacement generated in the structure or a part A thereof, and also a large number of them. The rotary plate 3 can significantly increase the damping force. Also, the rotary shaft 2
However, since the displacement extraction rod 5 is displaced in the arrangement direction, it is possible to avoid the interference with the rotary shaft 2 while increasing the diameter of the rotary disc 3, so that the shaft support rigidity of the rotary shaft 2 is increased. A higher damping force can be obtained by improving.

FIG. 4 shows still another embodiment of the damping device of the present invention, in which a motor 7 serving as a rotary drive source is connected to each of the rotary shafts 2. In this embodiment, the sensor 14 detects the relative displacement of the structure or a part A of the structure, and the controller 15 controls the rotational movement force exerted by the displacement on the rotary shaft 2 and the rotary disc 3 via the displacement extracting rod 5. Along with the calculation, a so-called active control is enabled by calculating a back torque against this rotational kinetic force and giving a control signal for generating it to the motor 7.

It is also possible to employ various displacement transmission mechanisms in place of the displacement transmission rod. For example, a rotary arm that rotates around a fulcrum is used as a lever, and the structure is constructed according to the ratio of the lengths of the lever. Alternatively, it is possible to appropriately increase or decrease the displacement of a part of the displacement and transmit the displacement to the displacement extracting rod.
