［産業上の利用分野］
本発明は、位置制御機能と振動吸収機能を有す

ものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vibration isolation/support mechanism for equipment in space, which has a position control function and a vibration absorption function.

の防振・支持機構としては、電磁サスペンシヨン
を用いることが考えられる。[Prior Art] Since the gravity on a flying object in space is significantly lower than on the ground, it is expected that materials with superior performance that cannot be produced on the ground will be produced. However, even on a flying object, vibrations occur due to human activities, machine movements, etc., and can have a negative impact on the properties of the materials being manufactured. It is necessary to prevent vibrations from being transmitted to the manufacturing device on the object as much as possible, and to support the manufacturing device on the flying object. It is conceivable to use an electromagnetic suspension as this vibration isolation/support mechanism.
しかし、地上用としては、多数の応用例のある
電磁サスペンシヨンも、宇宙における装置の防
振・支持機構に応用した事例はない。 However, although electromagnetic suspension has many applications on the ground, there are no examples of it being applied to vibration isolation and support mechanisms for equipment in space.
［発明が解決しようとする問題点］
宇宙における装置の防振・支持機構として上述
の電磁サスペンシヨンを適用することが考えられ
るが、宇宙における重力の加速度は、地上の重力

振・支持機構とは比較にならない高精度で、かつ
柔構造の防振・支持機構が必要である。[Problems to be Solved by the Invention] It is conceivable to apply the above-mentioned electromagnetic suspension as a vibration isolation/support mechanism for equipment in space, but the acceleration of gravity in space is smaller than the acceleration of gravity on Earth. For example, a device that weighs 100 kgf on the ground weighs only about 0.1 gf in space, so it has a high precision and flexibility that is incomparable to vibration isolation and support mechanisms on the ground. Structural vibration isolation and support mechanisms are required.
又、宇宙では、加速度の大きさや方向が変化す
るので、一定の強さや方向をもつ力で、装置を支
持して、バランスさせておくことはできない。 Furthermore, in space, the magnitude and direction of acceleration change, so it is not possible to support and balance the device with a force that has a constant strength and direction.
更に地上においては、地球方向への重力による
力が強いのに対して、宇宙では上下、左右の力の
強弱が殆んどなく、直角座標３軸にほぼ等方性が
あるため、地上とは異なる考え方で防振・支持機
構を開発しなければならない。 Furthermore, on the ground, the gravitational force is strong in the direction of the earth, whereas in space, there is almost no strength or weakness in the vertical, horizontal, or horizontal forces, and the three rectangular coordinate axes are almost isotropic, so the gravitational force is strong in the direction of the earth. Anti-vibration and support mechanisms must be developed using a different approach.
本発明は、上述の実情に鑑み、宇宙における装
置の防振・支持機構の高精度化、柔構造化を目的
として、なしたものである。 The present invention has been made in view of the above-mentioned circumstances, with the aim of increasing the precision and making the vibration isolation/support mechanism of equipment in space more flexible.

ている。[Means for Solving the Problems] The present invention comprises a cylindrical portion having an S pole or an N pole at its tip, and a rod-shaped portion fixed substantially coaxially within the cylindrical portion and having an N or S pole at its tip. It has six sets of electromagnetic suspensions each consisting of a permanent magnet and a coil that can be loosely fitted into the space formed between the cylindrical part and the bar-shaped part of the permanent magnet, and the rectangular coordinates 3 of the device to be supported are provided. Two permanent magnets each are arranged on the shaft so that their tips face outward with respect to the device to be supported, and each permanent magnet is fixed to the device to be supported. The coil is loosely fitted into the space formed between the cylindrical part and the rod-shaped part of each permanent magnet fixed to the device, and each coil is fixed to a support frame surrounding the device to be supported. A sensor is provided to detect the direction and magnitude of acceleration acting on the device or the displacement of the device to be supported, and the excitation current supplied to the coils of each electromagnetic suspension is controlled in response to an output signal from the sensor. A control device is provided.

By controlling the supporting force of the electromagnetic suspension, it is possible to support and dampen the supported device in response to weak steady acceleration in space and vibrational acceleration that changes in size and direction. .

急激に変化することがない。 In addition, a permanent magnet constituted by a cylindrical portion and a rod-shaped portion fixed substantially coaxially within the cylindrical portion, and a coil that can be loosely fitted into a space formed between the cylindrical portion and the rod-shaped portion of the permanent magnet. Therefore, since each electromagnetic suspension is formed, the permanent magnet can be displaced in both the axial direction and the circumferential direction of the coil, and even if the permanent magnet is displaced relative to the coil, it will not be a permanent magnet. The magnetic force that interacts with the coil does not change suddenly.

Therefore, even if the shape of the device to be supported is not axially symmetrical, it is possible to support the device in a stable state,
It is possible to provide vibration isolation for the above-mentioned device.

さに制御する。 In space, due to the shift from the center of mass and the slight residual atmospheric resistance, a completely weightless environment cannot be obtained, and there is a weak but constant acceleration in one direction. When mechanical equipment is used and manned operations are performed, vibration acceleration occurs due to vibrations of the mechanical equipment and human movements. When the supported device 1 moves due to such steady acceleration or vibrational acceleration, the permanent magnet 3a of the electromagnetic suspension 3, the south pole 3a -1 , and the north pole 3a
-2 's relative positional relationship changes. Each sensor 4 senses the magnitude, direction, or displacement of the acceleration when the positional relationship changes, and the control device 5 receives the output signal from each sensor 4 and controls each electromagnetic suspension corresponding to each sensor 4. The excitation current i supplied to No. 3 is controlled to a constant strength as shown in FIG.

られる。 The electromagnetic suspension 3 has the coil 3b wound in a uniform direction, and the permanent magnet 3a
Because the winding is wider than the effective width of the magnetic field generated by By controlling the excitation current i to a constant value, the change in overlap (displacement δ of the supported device 1)
Regardless of the condition, the supporting force P of each electromagnetic suspension 3 with respect to the supported device 1 is kept constant.

ように変化する。 In the above embodiment, the excitation current i is controlled to be constant so that the spring constant is almost 0, making it an extremely soft spring. However, the displacement of the supported device 1 is detected by the sensor 4, and the , the current may be changed. For example, excitation current i
By controlling so that i = i 0 + aδ (a is a constant), an arbitrarily soft spring with a spring constant a can be made. The supporting force P in this case changes as shown in FIG. 7 depending on the displacement δ.

Since each electromagnetic suspension 3 is formed by the coil 3b that loosely fits into the space formed between the S pole 3 a-1 and the N pole 3 a-2 of the permanent magnet 3a, the permanent magnet 3a can be displaced in both the axial direction and the circumferential direction of the coil 3b, and even if the permanent magnet 3a is displaced with respect to the coil 3b, there is an interaction between the permanent magnet 3a and the coil 3b.
