生原因ともなりうる。Excessive external force is applied due to fluctuations in wind pressure and vibrations of the rock (2) during earthquakes, and combined with the decrease in bending rigidity due to building heights, the building (1) is subject to extremely large vibrations. induced. Such excessive vibrations cause damage to the high-rise building (1), discomfort to people living in the high-rise building (1), and the resulting health problems. Furthermore,
Vibration propagation to the ground may loosen nearby buildings, residences, etc., causing great discomfort to nearby residents and causing vibration pollution.
こうした高層建築物（１）で生じる振動を低減するには
、従来、建築物（１）の補強による剛性の増大。In order to reduce the vibrations that occur in such high-rise buildings (1), conventional methods have been to increase the rigidity of the buildings (1) by reinforcing them.

。Alternatively, countermeasures such as installing a damper at the end of the auxiliary rope were taken, but these were not fundamental countermeasures.
そこでその改善策として第２図に示すマス・ダンパ一方
式の振動制御装置が提案されている。第２図は、従来の
振動制御装置を示す概略構成図で。Therefore, as a solution to this problem, a mass damper type vibration control device shown in FIG. 2 has been proposed. FIG. 2 is a schematic configuration diagram showing a conventional vibration control device.

物体を支承する車輪である。In the figure, (4) is a vibrating object, and (5) is a detection means for detecting the amount of vibration, which is composed of a sensor. (6) is a control device, (7) is a drive means that generates a control force, (8) is a mounting shaft that connects the drive means and the additional mass object (9), and +10+ is a wheel that supports the additional mass object.
今、振動物体（４）に振動が生じるとセンサー（５）が
これを検出し、その信号は制御装置（６）に送られる。Now, when vibration occurs in the vibrating object (4), the sensor (5) detects this and sends the signal to the control device (6).
制御装置（６）は駆動手段（７）に指令を出し、駆動子
ノは図中矢印で示した制御力Ｆ（ｔ）を発生する。この
制御力Ｆ（ｔ）は次式で与えられる。The control device (6) issues a command to the drive means (7), and the drive element generates a control force F(t) shown by an arrow in the figure. This control force F(t) is given by the following equation.

擦力が発生する。The generated control force F (t) is applied to the vibrating object (4) and at the same time as a force acting in reaction to this control force, it can be balanced by moving the additional mass object (9-) via the mounting shaft (8). . However, the additional mass object (9) is the wheel αO
), the weight of the additional mass acts on the wheel (10), and frictional force is generated as the additional mass object (9) vibrates.
この摩擦力は、駆動手段（７）から振動物体（４）に加
えられた制御力を減少させるように作用する。This frictional force acts to reduce the control force applied by the drive means (7) to the vibrating object (4).

の欠点があった。Since the conventional mass damper one-type vibration control device is configured as described above, it only has the function of reducing vibration in one direction in the horizontal plane.Therefore, in order to reduce vibration in two directions in the horizontal plane, It is necessary to install two vibration control devices at right angles, which increases cost and installation space. In addition, the control force generated by the drive means (7) does not work effectively due to the frictional force accompanying the vibrational movement of the additional mass object (9), and the device operates only for imaging amounts exceeding a certain level. There was a drawback.
この発明は上記のような従来のものの欠点を除去するた
めになされたもので、付加質量物体を。This invention was made in order to eliminate the above-mentioned drawbacks of the conventional ones, and it uses an additional mass object.

向の振動を低減し、付加質量物体の振動的動きが円滑な
振動制御装置を提供することを目的としている。By attaching one end to the driving means and suspending it within the vibrating object so as to be movable within the horizontal plane, a vibration control device is provided that reduces vibrations in multiple directions within the horizontal plane and allows smooth vibrational movement of the added mass object. It is intended to.

と格段に小さいことは言うまでもない。Next, the operation of the present invention will be explained. Vibrating object (4
), a photographing control force Fx(t) is generated based on the same principle as the conventional vibration control device shown in FIG. Furthermore, for the vibration of the vibrating object (4) in the X direction, Fy
(t) occurs. Here, the additional mass object (9) is suspended by a rope (12+), and the slider bearing (11) is inserted between the mounting shaft (8) and the additional mass object (9), so the additional mass object (9) is Since the mass object (9) can move smoothly in both the X and X directions, one additional mass object (9)
), it is possible to balance both the control force in the X direction and the control force in the X direction. That is, the vibrations generated in the vibrating object (4) in two directions within the horizontal plane can be reduced with one additional mass object (9). Furthermore, it goes without saying that the frictional force against the vibrational movement of the additional mass object (9) is much smaller than when it is supported by conventional wheels (10) because it is suspended by the ropes 12+.
