う不都合が生していた。(Prior Art) Conventionally, there are various types of devices for isolating and damping vibrations, including a 4-meter structure. However, in conventional devices that only have damping means such as orifices, the elastic mechanism inside the device is made as flexible as possible due to the need to further enhance the vibration isolation effect, so vibration damping is necessary. There is an extremely disadvantageous drawback in that vibrations, particularly free vibrations, are sustained indefinitely in the elastic mechanism itself, resulting in a reduction in the efficiency of vibration damping. In addition, in various conventional devices, it is common for the vibration generation source and the vibration damping mechanism in the device to be in harmonious contact with the debris, so the vibrations induced as appropriate due to this contact state. This is inconvenient in that the vibration is transmitted to the mechanism itself which is intended to dampen the vibration, and the mechanism itself becomes a vibration medium.

調節することができる。That is, since the ring-shaped cylindrical portion 12 is connected with each magnet body 21 with the same polarity facing each other via each spacer 22, each magnetic field 23 is generated as shown by the m line in FIG. The maximum and intense magnetism *24 (black dots in the figure) occurs at the side portions of each spacer 22, and the magnetic field is minimum at the center of each magnet body 21. Therefore, the vibration damping Jj in the device of the present invention is
In one structure (A), the inner circumferential surface of the ring-shaped cylinder part 21 and the inner circumferential surface of the ring-shaped cylinder part 21 are A magnetic field 24 can be applied extremely effectively to the magnetic fluid 15 flowing through the passage 14 formed between the outer peripheral surface of the inner cylinder 13, and the apparent viscosity of the magnetic fluid 15 is reduced by the MI field 24. This means that it will be possible to increase it even further. The apparent viscosity of the magnetic fluid 15 can be easily adjusted by changing the viscosity concentration of the magnetic fluid 15 by concentrating or diluting the magnetic fluid 15 itself.

As the magnetic fluid 15 moves along the vibration of the Jilli device, etc., the magnetic fluid 15 flows through the passage section 14 while creating a velocity gradient. A pressure difference proportional to the average velocity of the flow is generated, which generates a braking force, further increases the braking force, and uses this braking force to create a deployable mechanism (B). ), etc., can be quickly damped. According to the present invention, by combining the magnetic fluid 15 and each magnet body 21 as in the above example, the braking force itself, which depends on the viscosity of the magnetic fluid 15 and the gap between the passage portions 14, Due to the above-mentioned intense magnetic field 24, the apparent viscosity of the magnetic fluid 15 increases, adding an even greater braking effect, thereby instantly and highly efficiently suppressing the vibrations induced in the I# mechanism (B), etc. It is designed so that it can be attenuated.

。On the other hand, the present invention not only has a particularly excellent damping effect as described above, but also has a ring-shaped cylinder part 12 made of laminated magnets 21 in a magnetic fluid 15, and also Due to the strong magnetic field 24 generated on the inner circumferential side surface, the inner cylinder part 13 is centered on the waste without coming into contact with the inner circumferential surface of the ring-shaped cylinder part 12 at all. Therefore 1. In other words, the device can be called a non-contact type damping mechanism, and can completely eliminate the inconvenience that each mechanical part of the device itself becomes a vibration medium when contacted as in the conventional method. It is something.

A vibration damping mechanism (A) characterized by rapidly damping the free vibrations of the air and improving the transient characteristics and phase characteristics very well. An elastic mechanism (B) that has spring properties that are made as soft as possible by some appropriate means, including a spring method. The unique Q, r deployable mechanism (B) efficiently isolates the vibrations of equipment, etc., and at the same time, by skillfully combining the magnet body and magnetic fluid, the device itself can be made completely contactless. A device mount, etc., characterized in that the free vibration generated in the elastic mechanism (B), etc. can be instantly and highly efficiently damped by the vibration damping mechanism (A) described in E, which serves as a damping mechanism of the method. support device.
