Description of the Related Art An electrorheological fluid is a fluid whose viscosity changes according to an applied voltage, and has a characteristic that it has a fast response speed and consumes very little power. Japanese Unexamined Patent Publication (Kokai) No. 6-2731 is known to utilize this as a vibration damping means. This uses a cylinder as shown in Fig. 1 and causes a one-way flow in the electrorheological fluid by the movement of the piston and the action of the check valve, and this flow is the control gap between the cylinder and the tube concentrically arranged outside the cylinder. To use the outer surface of the cylinder and the inner surface of the tube as the corresponding electrode surfaces for the vehicle suspension system.
The damping force is adjusted by controlling the voltage applied to the electrode surface according to the vibration transmitted from the road surface and changing the fluid viscosity in the control gap.

体制振装置を提供することにある。However, the one using the cylinder as described above shows a strong dependence on the fluid velocity because the electrorheological fluid flows through the control gap at a high pressure and at a high speed. When used with, at high speeds you may experience a slipping condition like a broken chain. If the damping force is increased or the control gap is made smaller so that the damping force can be controlled even at a low voltage, the flow path area is reduced and a throttling effect unrelated to the applied voltage is generated. There is also a problem that it cannot be controlled over a wide range. In order to control a large damping force over a wide range without changing the interval, it is necessary to secure a large area for the control gap, and the device becomes large. The present invention was created in view of the above circumstances, and an object thereof is to provide an electrorheological flow vibrating device capable of obtaining a large damping force in a relatively small size and controlling the damping force over a wide range even at high speeds. It is in.

軸方向の減衰力に変換され、構造物の振動を制振する。When the slider of this device receives the vibration of the structure and moves in the expansion / contraction direction in the guide cylinder, the nut body at the slider tip, whose rotation is constrained by the slide key, is fixed at both ends of the casing via the screw shaft and the bearing. The central axis supported by the lid and the rotary body fixed to the central axis are reciprocally rotated. The electrorheological fluid is held in the control gap between the outer surface of the rotating body and the inner surface of the cylindrical body by an oil seal. When a voltage is applied to the electrode surface of the control gap, the viscosity of the electrorheological fluid increases, and a braking torque is applied to the reciprocating rotation of the rotating body. The braking torque of the rotating body is converted into a damping force in the axial direction of the slider by the screw shaft, the nut body, and the sliding key, and the vibration of the structure is damped.

る。The flow of the electrorheological fluid in this device is different from the cylinder that flows through the control gap at high pressure and high speed, and because of the resistance due to the so-called shear flow generated by the relative movement between the rotating body and the electrorheological fluid, the braking torque is increased. It has little speed dependence and can exert viscous effect even in high speed range. The electrode surface has a space of about 1 mm, and a voltage of 0 to several KV is applied from the external power supply and controller, but the current density is 0.
Power consumption is extremely low, about several tens of microamps / cm @ 2. The response speed of the braking torque is several msec to several tens msec.
Therefore, even if a random wave in which various kinds of vibrations are overlapped is received, the optimum damping force can be instantly generated according to the dynamic behavior such as the frequency, the speed, and the acceleration that changes every moment. Braking torque is generated in proportion to the outer diameter and length of the rotating body and the applied voltage, and acts on the central axis.Because the lead of the screw shaft provided in the extension of the central axis also serves as an element for increasing or decreasing the damping force. The device can be miniaturized.

油口１ｂから補充できる。The temperature and volume of the electrorheological fluid 10 change due to the ambient temperature and the damping action. This is because when the vibration damping device absorbs the kinetic energy of the structure, the kinetic energy is converted into heat energy, and in the case of the present device, the temperature of the electrorheological fluid rises. Therefore, a plurality of through holes 1a communicating with the fluid chamber 10a are provided on the same radial line of the cylindrical body 1,
An accumulator 11 made of rubber foam accumulated or a bellows-like metal bellows with both end plates attached was arranged. The accumulator 11 absorbs a change in volume of the electrorheological fluid 10, and prevents the electrorheological fluid 10 from being insufficient to generate a gas portion, which cannot be controlled, or the pressure increases to cause oil leakage. The electrorheological fluid 10 can be replenished from the oil supply port 1b communicating with one of the through holes 1a in which the accumulator 11 is not inserted.

When heat accumulates, the temperature rises, and there is concern that the material may deteriorate and the vibration damping function may deteriorate. Even if it is a vibration control device, some measures are required. In this device, a heat radiating plate 1c is formed on the outer peripheral exposed portion of the cylindrical body 1 so that the temperature does not rise even if the kinetic energy of the structure is continuously absorbed.

The member 2d and the pull tab 13a of the slider 13 are used by being connected to a structure or equipment. When the slider 13 of this device receives vibration of a structure or the like and moves in the guide tube 12 in the expansion / contraction direction, the nut body 14 at the tip of the slider 13 whose rotation is restricted by the slide key causes the screw shaft 6a and the bearing 4 to rotate. , 5 to reciprocally rotate the central shaft 6 supported by the lids 2 and 3 at both ends of the casing and the rotary body 7 fixed to the central shaft 6. The electrorheological fluid 10 is the oil seal 8 or the mechanical seal 9
Therefore, it is held in the control gap 10b between the outer surface of the rotating body 7 and the inner surface of the cylindrical body 1. When a voltage is applied to the electrode surface of the control gap 10b, the viscosity of the electrorheological fluid 10 increases, and a braking torque is applied to the reciprocating rotation of the rotating body 7. The braking torque of the rotating body 7 is converted into a damping force in the slider axial direction by the screw shaft 6a and the nut body 14 to suppress the vibration of the structure.

Unlike a hydraulic cylinder that flows through a control gap at high pressure and high speed, since it is a simple shear flow, there is little speed dependence of the braking torque, and there is no throttling effect that occurs regardless of the applied voltage. Therefore, the viscous effect can be exhibited even in the high speed region, and a large damping force can be controlled in a wide range. Further, the braking torque is generated in proportion to the outer diameter and length of the rotating body and the applied voltage and acts on the central axis, but the lead of the screw shaft provided in the extension of the central axis is also an element for increasing or decreasing the damping force. Therefore, the device can be downsized.
