Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an active mass type vibration damping device using a storage battery as a power source.

[0002]

2. Description of the Related Art As a method of damping the seismic force acting on a building, an additional mass type damping device has been often used. The additional mass type vibration damping device vibrates a weight, which is supported in the upper layer of the building so as to be able to swing with respect to the building, to vibrate so as to absorb the vibration energy of the building. There is a passive dynamic vibration absorber that absorbs energy in synchronization with the vibration cycle of the building, and an active vibration control device that enhances the vibration control effect by forcibly controlling the vibration of the weight by an electric motor or the like. .

[0003]

However, when an electric motor is used as an actuator of an active vibration damping device, a relatively large power supply capacity is required, and therefore an emergency power supply such as a constant voltage constant frequency device is required. The power supply cannot be supplied and the vibration control device does not operate during a power failure. However, because typhoons and other tremors continue for a long time, even if a power failure occurs, the vibration control device must continue to operate.

In addition, in the additional mass type vibration damping device, a weight of about 1% of the ground weight of the building is used, and as the weight, a weight made exclusively of iron or concrete is used. In recent years, in order to effectively use the space of a building, it has been attempted to utilize a part of a heat storage tank or a body as shown in Japanese Patent Laid-Open No. 1-322074.

In the present invention, a storage battery is used as the power source of the actuator so that the vibration damping device operates even during a power failure, and
(EN) A vibration damping device that uses a storage battery itself as an additional mass to effectively use the space of a building.

[0006]

In an additional mass type active vibration damping device, a means for vibrating the additional mass is provided so as to absorb vibration energy of a building, and the vibration of the additional mass is supplied to a storage battery as a power source. Controlled by an electric motor actuator.

Further, the storage battery itself can be used as an additional mass.

Further, the additional mass can be realized as a composite type with a passive type in which a laminated rubber bearing is supported and a damper is arranged.

[0009]

In the additional mass type active vibration damping device, by using the storage battery as the power source of the actuator by the electric motor, the vibration damping device can continue to operate even during an emergency power failure. In addition, since the storage battery is charged with a power source that is sufficiently larger than the power supply required to charge the storage battery and operate the vibration damping device with midnight power, part of the power can be used as the power source for the building through the DC / AC converter. Is.

Further, the storage battery itself is used as an additional mass,
It is also possible to contribute to the effective use of the space of the building.

Further, although the above-mentioned active vibration damping device is a method of actively damping vibration, there is a complication that the scale of the device varies depending on the degree of the earthquake to be damped. By using the laminated rubber bearing and the damper together with the passive vibration damping device, efficient vibration damping can be achieved according to the characteristics of the respective vibration damping devices.
