Therefore, if the maximum performance of the equipment is determined for frequent small- to medium-sized earthquakes or typhoons with wind speeds of 15 m/s or less, it is necessary to prevent the equipment from overworking in the event of a large-scale earthquake. must not. Therefore, it is necessary to suppress the control force when large-scale building vibrations occur.

制御を行うことができる。 Further, by providing an automatic gain adjustment circuit in the amplifier circuit for amplifying the response signal from the building side, 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. Then, 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. After all, regardless of the magnitude of the building's vibrations, the vibration damping system performs control within a certain range of capabilities, so during periods of strong shaking, the weight moves almost integrally with the building (it is stationary relative to the building). ), the safety of the equipment is maintained without receiving a large force from the building, and when the earthquake etc. subsides and the vibration of the building decreases, the amplification factor of the response signal on the building side increases again due to the action of the automatic gain adjustment circuit. This enables control to effectively suppress building vibrations.

In other words, if the vibration of the building exceeds the capability of the vibration damping device, it should be controlled within the capability of the vibration damping device, and if the vibration is even larger, the relative movement between the weight and the building should be reduced. This ensures the safety of the equipment.

ができる。 The weight of the vibration damping device must be driven within the capacity of the device, and there is a limit to its amplitude.However, vibrations on the building side vary depending on the scale of the earthquake, ranging 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, control is performed that is 90° out of phase with the vibration of the building, whereas when the acceleration on the building side is large, control approaches the movement of the building. Since the acceleration on the building side is large, the control is almost synchronized with the vibration of the building, that is, the hydraulic cylinder does not operate and the weight is in a state of stopping 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 accelerate vibration damping of the building.

When this happens, the amplification factor of the response signal on the building side decreases, and the vibration damping device is virtually inactive while the shaking is large, and the weight remains stationary relative to the building, so it receives a large force from the building. equipment safety is maintained without
When the earthquake, etc. subsides and the vibration of the building becomes smaller, the amplification factor of the response signal on the building side increases again due to the action of the automatic gain adjustment circuit, and the control force is applied in the direction of suppressing the vibration of the building.
