本発明は振動制振システムに係り、特に微少振動の伝達
を能動的に制御する装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vibration damping system, and particularly to a device that actively controls the transmission of minute vibrations.

変更や振動体の物理定数を大幅に変更することが余儀な
くされる。最も手近な方法として振動伝達率を少なくし
、加えて振動体系に減衰を与える方法がとられていた。Vibration is transmitted to the non-vibrating body between the vibrating body that receives the disturbance and the non-vibrating body that engages and functions to suppress the vibration.
Generates vibration and noise. In particular, when the natural frequency of the vibrating body and the excitation frequency match, causing elastic wave vibration and creating a resonant state, vibration and noise increase, which becomes a problem. When such a state occurs, it is difficult to get out of this state by reducing the excitation source to a smaller number, and it becomes necessary to make a major structural change or to significantly change the physical constants of the vibrating body. The most convenient method was to reduce the vibration transmissibility and, in addition, provide damping to the vibration system.
しかしながら、このような方法では非振動体自体の重量

低下を招いていた。また従来の方法では制振する周波数
範囲にも限界があった。これらの問題は古くから対策は
なされてきたがいずれも受動的な割振装置であり、上述
のような問題点をもって今日に至っている。However, with this method, it is extremely difficult to suppress vibrations when the weight of the non-vibrating body itself is extremely reduced, and a method to further reduce the transmissibility is to reduce the spring constant of the supporting elastic body. However, there is a point L where the stability of the non-vibrating body deteriorates due to the increased deflection of the elastic body due to the applied load, leading to a decline in product performance depending on the magnitude of the load. Furthermore, conventional methods have limitations in the frequency range in which vibrations can be suppressed. Measures have been taken to address these problems for a long time, but all of them are passive allocation devices, and they still have the problems described above.
この発明の目的は、上記問題点を解消するためになされ

を提供することである。The purpose of this invention was to solve the above-mentioned problems, and it actively suppresses vibration by absorbing vibration force within a support device interposed between a vibrating body and a non-vibrating body. An object of the present invention is to provide a vibration prevention device that reduces vibrations transmitted to a non-vibrating body.

されることを特徴とするものである。In order to achieve the above object, the vibration prevention device of the present invention includes:
In a system in which a support device is interposed between a vibrating body and a non-vibrating body, and vibration is transmitted from the vibrating body to the non-vibrating body via the support device, an electromagnet is combined in parallel with a part of the support device. and an elastic body to control a detection signal from a vibration detection means disposed on the non-vibrating body, and to actively control a gap between the electromagnet and a counter electrode of the electromagnet by the control signal. This is a characteristic feature.
上記の構成によると、振動体の振動が支持装置を介して
非振動体に振動力を伝達するときに、この振動力が支持
装置内で吸収される。すなわち、電磁石と弾性体とを並
列に構成した支持装置が介在しているので、振動体が振
動すればその振動に相当する変化を非振動体の振動が小
さくなる方向へ電磁石の空隙を変化せしめ、結果として
、振動体の振動は非振動体に伝達しないことになる。According to the above configuration, when the vibration of the vibrating body transmits vibration force to the non-vibrating body via the support device, this vibration force is absorbed within the support device. In other words, since there is a support device in which an electromagnet and an elastic body are arranged in parallel, when the vibrating body vibrates, the gap between the electromagnets changes in the direction that the vibration of the non-vibrating body becomes smaller. , As a result, the vibration of the vibrating body is not transmitted to the non-vibrating body.
この際、制御する電磁石の対極との空隙を変化させる力
は印加する電圧（電磁石の吸収力は電流Ｘ巻線数で決ま
るから一定周波数においては電圧に比例する。）により
制御され、この制御方式は。At this time, the force that changes the air gap between the controlled electromagnet and the opposite pole is controlled by the applied voltage (the absorption power of the electromagnet is determined by the current x the number of turns, so it is proportional to the voltage at a constant frequency), and this control method teeth.

の位相と振動振幅とを制御して、電磁石の入力信号とし
、この電磁石の吸収力と反撥力が非振動体の振動が最も
小さくなるように作用し、その結果として非振動体の振
動が防止される。The phase and vibration amplitude of the signal waveform are controlled by the detection signal of the vibration detector installed on the non-vibrating body, which is used as an input signal to the electromagnet, and the absorption force and repulsive force of this electromagnet minimize the vibration of the non-vibrating body. As a result, vibration of the non-vibrating body is prevented.
以下、本発明の実施例を図面に基づいて説明する。 Embodiments of the present invention will be described below based on the drawings.

間隙が能動的に制御されるようになっている。In FIG. 1, a support device 3 is interposed between a vibrating body 1 and a non-vibrating body 2. In FIG. An electromagnet 4 and a rubber 5 as an elastic body are provided in a part of this support device E3~, which are combined in parallel, and detect a detection signal from a detector 6 which is a vibration detection means disposed on the non-vibrating body 2. The control signal is controlled by a controller 7, and the gap between the electromagnet 4 and the opposing magnetic pole 8 is actively controlled by this control signal.
なお、図中９と１０は電磁石４を構成する継鉄とコイル
である。対向磁極８も継鉄でできている。In addition, 9 and 10 in the figure are a yoke and a coil that constitute the electromagnet 4. The opposing magnetic pole 8 is also made of a yoke.

スヘッド１７に支持装置３を介して伝えられる。FIG. 2 shows a specific example in which the present invention is applied to an elevator, in which a vibration-proof rubber 12 is provided on an outer frame 11, and a seat heel 13 is supported. On the other hand, power is transmitted to the outer frame 11 from a hoisting machine (not shown) via a rope 14.
is terminated by an elastic body 15 and a hanging plate 16. The force for raising and lowering the elevator from the rope 14 is transmitted to the crosshead 17 via the support device 3.

へラド１７の間に設けたところにあり、以下具体的に動
作機能を説明する。Here, the hanging plate 16 corresponds to the vibrating body 1 in FIG. 1, and the cross plate 17 corresponds to the non-vibrating body 2. In such a system, the part to which the present invention is directed is the part where the support device 3 is provided between the hanging plate 16 and the cross plate 17, and the operating function will be specifically explained below.

れる。In FIG. 2, when the suspension plate 16 vibrates due to vibrations propagated from the rope system, the vibrations are transmitted to the crosshead 17 through the support device 3. Further, referring to FIG. 1, the transmitted vibration is detected as a signal output from the detector 6. The signal output is applied to the coil 10 by the controller 7 so that the signal output of the detector 6 becomes small.
支持装置３として、本実施例では、継鉄８と継鉄９に対
向させゴム５を挟持させゴム５の厚みによって空隙Ｔを
確保でる構成になっているため、印加電圧の変化に応じ
て空隙Ｔは変化し目的を達成できる。In this embodiment, the support device 3 is configured such that the yoke 8 and the yoke 9 are opposed to each other and the rubber 5 is sandwiched between them, and the gap T is secured by the thickness of the rubber 5. T can change and achieve his goals.
第１図及び第２図に示した磁石の両端の空隙績に挟持し
たゴムによる空隙の変化のようすを更にわかりやすくす
るため第３図を用いて説明する。In order to make it easier to understand how the gap changes due to the rubber sandwiched between the gaps at both ends of the magnet shown in FIGS. 1 and 2, it will be explained using FIG.
いま吊り板１６（振動体１）は引き上げられる方向に力

はＴ−ΔＴになる。Now, a force is acting on the hanging plate 16 (vibrating body 1) in the direction of pulling it up, but a force is being applied downward to the crosshead 17 (non-vibrating body 2) due to the weight of the car 13.
The rubber 5 held between the electromagnets shrinks and the gap becomes T. However, since the yoke 9 constituting the support device 3 is a permanent magnet, it further attracts the opposite pole, and the gap is reduced by ΔT, and becomes T-ΔT in darkness.
このようにしておけばコイル１０に制御信号が印加され
ると第３図に示したように中立軸に対して上下方向に空
隙の変化が起こる。ΔＴはロープ系より伝播される振動
振幅によって設定しておけばよい。With this arrangement, when a control signal is applied to the coil 10, the air gap changes in the vertical direction with respect to the neutral axis, as shown in FIG. ΔT may be set based on the vibration amplitude propagated from the rope system.
このことから電磁石を支持装置として用いた目的は達成
できることは明らかである。永久磁石についても直流用
コイルを用い直流励磁して使用すれば永久磁石を用いる
必要のないことは勿論である。It is clear from this that the purpose of using an electromagnet as a support device can be achieved. Of course, there is no need to use a permanent magnet if a DC coil is used and DC excitation is used for the permanent magnet.
次に他の実施例として第４図で説明する。Next, another embodiment will be explained with reference to FIG.
力の伝達は第１図の場合と全く同じであるが。The force transmission is exactly the same as in Figure 1.

is no longer necessary, and there is no need to insert rubber or the like into the gap between the electromagnets, and the gap between the electromagnets can simply be left as a gap.

It is possible to pass. Further, by locating the void on the outer periphery, the above configuration can be achieved.
この構成にすれば非常に小型化が図れるため、シングル
ロッド個々に取りつけることも可能になる。With this configuration, it is possible to achieve a very small size, and it is also possible to attach each single rod individually.

白である。The above has briefly described the vibration isolation of elevators, but it goes without saying that the present invention is effective for vibration isolation of, for example, vibration isolation tables of electron microscopes and semiconductor memory manufacturing equipment. - As an example, assume a platform on which the vibrating body 1 of Fig. 1 is installed,
It is clear that the above-mentioned effects can be obtained by mounting an electron microscope or semiconductor manufacturing equipment on a portion corresponding to the non-vibrating body 2.

微々たるものとなる。According to this specific example, the vibration transmitted from the rod 53 is reduced and transmitted to the hanging plate 16, and is further attenuated by the elastic body 61, so that the vibration transmitted to the crosshead 17 becomes insignificant.

The detection signal from the vibration detection means is controlled, and the gap between the electromagnet and the opposite pole of the electromagnet is actively controlled by the control signal, so vibration transmission to a non-vibrating body can be actively controlled, making it lightweight.
