In order to put this technology to practical use, various innovations are necessary,
In particular, it is an indispensable element to set (tune) the natural frequency of the pendulum vibration and the natural frequency of the vibration to be suppressed of the attached structure to be substantially equal.

り付けられる。FIG. 5 is a diagram showing a basic structure of a structure vibration control device. In the drawing, the inverted pendulum is configured by pin-supporting the lower end of the support column 52 holding the weight 51 at the upper end by the pin support portion 54 of the structure 53. Further, another support structure 55 is fixed to the structure 53, and the support structure 55 and the support 5
A spring 56 is attached between the spring and the No. 2 and the natural frequency of the inverted pendulum is adjusted according to the spring constant. If necessary, a damper 57 is attached to the spring 56 to add damping force.

保が困難になっていた。By the way, the steel spring often used as the spring 56 is individually manufactured in accordance with the required natural frequency, and it is difficult to change the spring constant of the spring 56 after mounting it on the vibration control device. Further, when trying to control the vibration of a large acceleration, the size of the spring 56 becomes large, which causes manufacturing difficulty. Furthermore, since the vibration control device using it also becomes large, the installation space is limited.For example, a vibration control device that requires a large damping force to suppress large vibrations caused by a large earthquake is Was difficult to secure.

A vibration control device (dynamic vibration absorption device) has been proposed which is attached to a device and absorbs vibration by utilizing the horizontal spring characteristic of the laminated elastic body. A vibration control device has also been proposed, which is configured by a multi-stage laminated elastic body unit in which upper and lower ends of a plurality of laminated elastic bodies are sandwiched and connected by stabilizers and are stacked in a plurality of stages.

大制振力が得られることが特徴になっている。The conventional laminated elastic body used in such a vibration control device uses a normal viscoelastic body having a constant rigidity regardless of strain, and a structure having a small amplitude can be used. It is designed to tune with the natural frequency of. That is, the conventional vibration control device can operate with respect to a small external vibration force by utilizing the mechanism of the laminated elastic body with less friction, and can obtain a large damping force with a relatively compact size. It is a feature.

周期で取り替えなければならなかった。However, even if such a vibration control device is installed for the purpose of suppressing the vibration of a large acceleration, it responds to a small vibration for which damping is not necessary, and the laminated elastic body is repeatedly damaged. It was unavoidable that extra was accumulated. In other words, the durability of the vibration control device installed in preparation for a large earthquake or storm that causes a large vibration to the structure, although the frequency of occurrence is extremely low, is impaired due to the high frequency of small vibration, and inspection is difficult. It was frequently needed and in some cases had to be replaced at relatively short intervals.

By using a material whose rigidity changes as it becomes, it is possible to construct a pendulum whose natural frequency changes depending on the amplitude. Therefore, when the structure shakes significantly due to a large earthquake and the external force acting on the pendulum exceeds a specified value and the pendulum is shaken to a specified amplitude, the pendulum's natural frequency tunes to the structure's natural frequency for the first time. Then, the resonance can be started to exert the vibration damping effect. That is, since a resonance phenomenon does not occur with respect to a small vibration, repeated damage is not accumulated repeatedly on the laminated elastic body, and durability can be significantly improved.

It is fixed integrally. The laminated elastic body 11 having such a structure has extremely high rigidity (spring constant) in the vertical direction and relatively low useful rigidity (spring constant) in the horizontal direction.

Materials of this type have already been developed, and for example, a high-damping laminated rubber made by Bridgestone Co., whose rigidity rapidly and drastically decreases as the strain increases, can be used. Such viscoelastic body 21
Fig. 3 shows the characteristics of rigidity (shear elastic modulus) with respect to strain (shear strain). The shear strain is a value (x / H) of the deformation amount x with respect to the height H of the laminated elastic body as shown in the figure.

ることができる。According to the characteristics shown here, the spring characteristics of the pendulum are adjusted in advance so that the natural frequency when a large amplitude is generated in the pendulum is tuned to the natural frequency component to be damped in the structure. By doing so, the natural frequency of the pendulum changes when the structure shakes greatly and the pendulum is forcibly shaken to a predetermined amplitude due to a large earthquake and the strain of the laminated elastic body increases. Then, the resonance frequency can be started by synchronizing with the natural frequency of the structure, and the damping effect can be exhibited.

装置を実現することができる。On the other hand, with respect to small vibrations during frequent small and medium-sized earthquakes and normal winds, the resonance phenomenon does not occur because the natural frequencies of the pendulum and the structure are not synchronized. Therefore, the repeated elastic damage does not accumulate on the laminated elastic body, and it can be operated only when a large damping force is required such as during a large earthquake, and it is a practical structure vibration control with significantly improved durability. The device can be realized.

For such structures, by combining viscoelastic bodies with different strain-to-rigidity characteristics, the degree of change in the natural frequency is adjusted by the amplitude, and tuning is performed within the required amplitude range to achieve a large damping effect. You can also get it.

Moreover, it becomes possible to realize a structure vibration control device having a large damping force.

Since it can be stopped, the durability can be dramatically improved.
