A hydraulic cylinder is interposed. When vibrations occur in the building 1 due to earthquakes, wind, etc., the sensor 4b installed in the building 1 senses the vibrations, sends a signal to the control circuit, and outputs a signal corresponding to the vibration of the building 1 to the actuator. 3 to control the actuator 3. In addition,
By providing the sensor 4a also on the actuator 3 side, the movement of the actuator 3 can be controlled by feedback. Additionally, although the above is closed-loop control, it can also be combined with open-loop control, which predicts and controls the building's response by analyzing seismic waves sent from wide-area and narrow-area seismometers.

ことにより、さらに効果的な制震が可能となる。 Furthermore, depending on the design of the building, relatively large effects can often be obtained even with control in only one direction.
External forces such as earthquakes and wind are uncertain external forces, and in eccentric buildings, more effective vibration damping can be achieved by suppressing torsional vibration components.

In Japanese Utility Model Application Publication No. 59-11315, for an additional mass that moves freely in a plane, actuators are installed at two positions approximately equal in distance from the center of inertia of the additional mass, and both horizontal vibration and torsional vibration are generated. An active vibration control device configured to control is described.

れる。 However, in the case of the device described in Japanese Utility Model Application Publication No. 59-11315, two actuators are provided for one additional mass, and the rotational inertial mass of the additional mass is used as a reaction force, making the additional mass rotatable. In addition to supporting
The connection part with the actuator must also have a structure that can follow the rotation of the additional mass.
The structure of the device becomes complicated. Furthermore, in addition to the structural complexity, there is also the complexity of controlling horizontal vibration and torsional vibration simultaneously, and adverse effects such as errors, control delays, and accompanying oscillations can be considered from both the structural and control perspectives.

is the acceleration, which is 90° out of phase with the velocity,
Mechanical parts such as hydraulic cylinders have mechanical delays due to friction and other factors, so if necessary, the phase is adjusted by 90° using an integrating circuit, and then adjusted to zero using a phase adjuster.
Make adjustments in the range of ~90°. The signal level is then adjusted by an amplifier.

なり、建屋の振動減衰を早めることができる。 The vibration of the weight of a seismic damping device must be within the capacity of the device, and there is a limit to its amplitude.However, the vibration of the building side varies depending on the scale of the earthquake, from small accelerations to large accelerations. There are even things. Therefore, an automatic gain adjustment circuit is installed on the building side, but when the acceleration on the building side is small, the amplification factor in the building side circuit increases, and as the acceleration on the building side increases, the amplification factor in the building side circuit increases. becomes smaller. As a result, when the acceleration on the building side is small, it responds to the vibration of the building and the phase is 90°.
In contrast to deviated control, when the acceleration on the building side increases, control approaches the movement of the weight,
Since the acceleration on the building side is large, the control is performed in synchronization with the vibration of the building, that is, the hydraulic cylinder does not operate, and the weight appears to be stationary relative to the building. When the acceleration on the building side decreases, the amplification factor in the circuit on the building side increases again, making it possible to speed up the vibration damping of the building.

After passing through a low-pass filter and a buffer amplifier, the difference is taken by a composite amplifier, and the same adjustment operation as input 2 above is applied to the torsional vibration component. The control signal for the weight of the auxiliary vibration damping device is output via the automatic gain adjustment circuit.

を行うことができる。 In this embodiment, an automatic gain adjustment circuit is provided in the amplifier circuit for amplifying the response signal from the building side, so that the level of the signal when combined with the amplified response signal from the weight side is adjusted. Therefore, in a range where the vibration of the building is not so large, the amplification factor of the response signal on the building side is large, so that control is performed in accordance with the vibration of the building. As the vibration of the building increases, the amplification factor of the response signal on the building side decreases, and the contribution rate of the movement of the weight side in control increases. In this state, the vibration of the building is large, but since the vibration damping device is controlling within a certain range of capabilities, the vibration of the weight gradually approaches the vibration of the building, and the control is also controlled so that it approaches the vibration of the building. . As a result, during strong shaking, the weight moves almost integrally with the building (staying stationary relative to the building), and the safety of the device is maintained without receiving large forces from the building. When the earthquake subsides and the vibration of the building becomes smaller,
Again, the automatic gain adjustment circuit increases the amplification factor of the response signal on the building side, and it is possible to perform control such that vibration is applied in the opposite direction to the vibration of the building, thereby speeding up the attenuation of the vibration.

づけることにより装置の安全が図れる。 Furthermore, as for the output of the composite signal, the output level of the composite signal is further adjusted by an automatic gain adjustment circuit, so that the vibration control device does not operate excessively even in response to excessive vibrations of the building. In other words, if the vibration of the building exceeds the ability of the vibration damping device, it will be controlled within the range of the vibration damping device's ability, and if the vibration is even larger, the vibration of the building will be controlled by bringing the movement of the weight closer to the movement of the building. safety can be ensured.

In this invention, two vibration damping devices, a main vibration damping device and an auxiliary vibration damping device, are provided as active vibration damping devices.The main vibration damping device controls horizontal vibration, and the other auxiliary vibration damping device controls vibrations in the horizontal direction. By suppressing torsional vibration, even in an eccentric building, vibrations of the building due to earthquakes etc. can be efficiently suppressed.
また、水平振動とねじれ振動を、別々の制震装
置で抑制するため、制御回路が単純化され、これ
らが相互に悪影響を及ぼす恐れが少ない。 Furthermore, since horizontal vibration and torsional vibration are suppressed by separate vibration damping devices, the control circuit is simplified and there is less risk that they will have a negative effect on each other.

The additional mass of the seismic device can be reduced, and the entire device can be downsized.
