Abstract

<P>PROBLEM TO BE SOLVED: To alleviate vibration in a living quarter without employing a mass damper type vibration control device. <P>SOLUTION: A tower construction 1 is formed by supporting the living quarter 3 on a support frame 4 mounted on a tower construction body 2 so as to be driven in an ascendable/descendible manner, in a manner displaceable in an optional direction in the horizontal plane. Then actuators 5a, 5b are interposed in a gap between the support frame 4 and the living quarter 3, and a controller 7 for issuing a control instruction to the actuators 5a, 5b, based on an input signal from an acceleration sensor 6 for detecting vibration of the support frame 4, is provided for the tower construction. Thus when the support frame 4 experiences vibration together with the tower construction body 2, the living quarter 3 is relatively displaced on the support frame 4 with a similar amplitude and in an opposite phase with respect to absolute displacement by vibration of the support frame 4, by the actuators 5a, 5b controlled by the controller 7, and therefore response to the displacement in an absolute space in the living quarter 3 is reduced. <P>COPYRIGHT: (C)2009,JPO&amp;INPIT

Description

  The present invention relates to a vibration isolation method and apparatus for a structure residential area that is used to reduce shaking due to an external force such as a wind external force of the residential area in a tower-like structure.

  In general, a tower-like structure is a flexible structure with small attenuation, so that it is likely to be shaken by an external wind force. When such a tower-like structure is shaken, a residential area (cabin) of the tower-like structure is generated. ) The people inside may get drunk. Moreover, when the height of the structure is increased, the vibration due to the wind load is more problematic than the earthquake load. Therefore, it is an important technical problem to reduce the wind fluctuation in the residential area in the tower structure.

  Conventionally, as a measure to reduce the shaking generated in a high-profile structure such as a tower-like structure, a movable mass that can move in the horizontal direction is provided on the upper part of the structure to be controlled. It has been proposed to install a mass damper system damping device.

  The mass damper system damping device is classified into an active system and a passive system depending on the presence or absence of an actuator that drives a movable mass. Among them, the passive vibration damping device is a vibration system in which a spring element and a damper element are attached to a movable mass movable in the horizontal direction, and the natural frequency of the vibration system is determined as a structure to be subjected to vibration damping. Is set to be equal to the natural frequency. According to a passive vibration damping device having such a configuration, when the structure is shaken, the movable mass naturally moves along with the shake so that the shake of the structure can be reduced.

  On the other hand, an active vibration control device detects vibration of a structure to be controlled by a sensor, and based on the detection signal, actively drives a movable mass using an actuator, thereby suppressing the vibration of the structure. It is made to reduce (for example, refer patent document 1 and patent document 2).

  In both the active and passive mass damper type damping devices, the mass of the movable mass is usually about 0.5% to 1% of the generalized mass of the structure to be damped. Since the mass is compact, it has been applied to many structures.

  However, in the actual application of the mass damper type damping device as described above, there is an installation space that allows for the stroke when the movable mass is reciprocated in the horizontal direction according to the vibration of the structure to be controlled. It is necessary, especially as the height of the structure increases, the required stroke of the movable mass increases, so in a narrow tower structure where the interior is occupied by machinery such as an elevator. Actually, it is difficult to secure the installation space.

  In addition, when the purpose is to reduce the wind fluctuation, the mass damper type vibration damping device described above is structured in consideration of the fact that the wind force is increased due to the larger wind force acting on the upper part than the lower part of the structure. Although it is desirable to install it at the upper part of the structure, if it is necessary to install it at the middle or lower part of the structure due to restrictions, it is necessary to increase the mass of the movable mass, or the performance will be reduced. .

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIGS. 1 to 4 show an embodiment of the vibration isolation device for a structure residential area according to the present invention, and an annular residential area (cabin) 3 can be moved up and down on the outer periphery of a tower-like structure body 2 extending in the vertical direction. In the case of applying to a tower-like structure 1 such as an observation tower of the type provided for, generally speaking, an annular support frame 4 is arranged on the outer periphery of the tower-like structure body 2, The support frame 4 is attached to the tower-like structure body 2 so as to be driven up and down. Further, the annular residential area 3 is supported above the support frame 4 so as to be displaceable in all directions within a horizontal plane, and an actuator 5 is interposed between the support frame 2 and the residential area 3. By providing the actuator 5, the living area 3 can be moved relative to all directions in the horizontal plane on the support frame 2. Further, a sensor 6 for detecting the shaking of the support frame 4 that shakes together with the shaking of the tower-like structure body 2 and a control command to the actuator 5 according to an input signal from the sensor 6. Assume that the controller 7 is provided.

  Details will be described below.

  The support frame 4 has a shape that projects from the planar shape of the living area 3 in the form of a ring to the inner circumference side and the outer circumference side, specifically, with the shaking of the tower-like structure body 2. The support frame 4 that swings together has a ring shape projecting from the planar shape of the living area 3 to the inner diameter side and the outer diameter side by a size corresponding to the maximum amplitude assumed.

  The inner peripheral end of the support frame 4 is provided with a cylindrical inner peripheral frame 4a extending in the vertical direction to a position slightly higher than the upper end of the living area 3 supported on the upper side of the support frame 4. Guide blocks 8 respectively installed at upper and lower end portions at required locations on the inner peripheral surface of the inner peripheral frame 4a, for example, four locations at equal intervals in the circumferential direction, and the like in the circumferential direction of the outer peripheral surface of the tower-like structure body 2 and the like. It is configured to be slidably attached to the vertical guide rails 9 provided at four intervals.

  Furthermore, as the raising / lowering drive mechanism 10 of the support frame 4, for example, one end is connected to each guide block 8 attached to the upper end of the inner peripheral frame 4a of the support frame 4, and the other end is connected to the tower-like structure. A drive rope 13 provided on the top of the tower-like structure body 2 with a wire rope 12 connected to a counterweight 11 that can be moved up and down inside the object body 2 and can be driven forward and backward by a drive device (not shown). The elevating drive mechanism 10 having a configuration hung around is provided, and the drive pulley 13 is driven forward and backward by the drive device (not shown) so that the support frame 4 is connected to the tower structure via the wire rope 12. It can be moved up and down along the outer surface of the object body 2.

  On the upper surface of the support frame 4, the linear guide 14a is placed at one of two required directions (xy directions) orthogonal to each other in a horizontal plane at a required location, for example, four locations in the circumferential direction as shown in FIG. And the ring shape similar to the bottom shape of the residential area 3 on the slider 15 of each linear guide 14a. An intermediate plate 16 is placed and attached. Further, the linear guide 14b is placed at a required place on the upper surface of the intermediate plate 16, for example, at four places in the circumferential direction as shown in FIG. 4B, the other of the two directions (xy directions) orthogonal to each other in the horizontal plane. (The vertical direction in FIG. 4B, hereinafter referred to as the y direction), and the residential area 3 is mounted on the slider 15 of each linear guide 14b. As a result, the intermediate plate 16 slides in the x direction via the linear guides 14a on the support frame 4, and the living area 3 moves in the y direction via the linear guides 14b on the intermediate plate 16. By combining the slide, the living area 3 can be displaced on the support frame 11 in an arbitrary xy direction, that is, in all directions in the horizontal plane.

  Further, a required place on the upper surface of the support frame 4, for example, two places facing 180 degrees in the circumferential direction as shown in FIG. 4 (a), is connected to the drive motor 17 and its output shaft as an actuator 5 a. A screw shaft 18 and a nut 19 screwed on the screw shaft 18 are provided, and the nut 19 can be moved in the axial direction of the screw shaft by forward and reverse rotation of the screw shaft 18 by the drive motor 17. Ball screw type actuators 5a that can be provided are provided along the x direction, and the nuts 19 of the actuators 5a are attached to the corresponding positions on the lower surface of the intermediate plate 16, respectively. In addition, ball screw type actuators 5b having the same configuration as the actuator 5a are provided at required positions on the upper surface of the intermediate plate 16, for example, two positions opposed to the circumferential direction as shown in FIG. The nuts 19 of the respective actuators 5b are attached to the corresponding positions on the lower surface of the residential area 3 respectively along the y direction. As a result, the actuator 5a drives the intermediate plate 16 in the direction along the x direction on the support frame 4, and the actuator 5b drives the living area 3 along the y direction on the intermediate plate 16. By combining with the driving to the above, the control force can be applied to the living area 3 in an arbitrary xy direction with respect to the support frame 4, that is, an arbitrary direction in a horizontal plane.

  Furthermore, in order to prevent the wind from directly hitting the residential area 3 provided on the support frame 4 and to ignore the movement (behavior) of the residential area 3 due to the direct action of the wind force. As shown in FIG. 1, a cylindrical outer peripheral frame 20 that extends in the vertical direction at the outer peripheral end of the support frame 4 and covers the outer peripheral side of the residential quarter 3 to a position slightly higher than the upper end of the residential quarter 3. And a ring-shaped ceiling frame 21 that covers the upper part of the residential area is attached between the upper ends of the outer peripheral frame 20 and the inner peripheral frame 4a.

  In addition, the length dimension (stroke) of each said linear guide 14a, 14b and each actuator 5a, 5b in FIG.2, FIG.3, FIG.4 (b) (b), the residential area 3, and the inner peripheral edge part of the intermediate | middle plate 16 The interval between the inner frame 4a of the support frame 4 and the interval between the outer peripheral end of the living area 3 and the intermediate plate 16 and the outer frame 20 is for convenience of illustration and reflects actual dimensions. is not.

  As the sensor 6 for detecting the shaking of the support frame 4, the acceleration sensor 6 is installed at a required portion of the support frame 4.

  When the detection signal of the acceleration of the support frame 4 is input from the acceleration sensor 6, the controller 7 is based on the following control theory in order to reduce the shaking of the residential area 3. , 5b is given a control command. The controller 7 determines the relative displacement direction, displacement amount, and displacement speed of the living area 3 on the support frame 4, that is, the rotational speed of the drive motor 17 of each actuator 5 a, 5 b, that is, the screw shaft 18. It is assumed that detection is possible from the position, moving direction, and moving speed of the nut 19 based on the number of rotations.

That is, the tower-like structure main body 2 and the support frame 4 and the residential area 3 are as shown in FIG. 5, and the mass of the residential area 3 is m ₁ and the mass of the tower-like structure main body 2 and the support frame 4 is m _2. The actuators 5a and 5b are inserted between the two mass points, and the control force is fc. In FIG. 5, the spring element k1 and the damping element c1 are combined in parallel with the actuators 5a and 5b, but only the actuators 5a and 5b may be used.

When the wind force f acts on the mass of the tower-like structure main body 2 and the support frame 4 on m ₂ , consider the case where the shaking of the residential area 3 is reduced by active control.

The equation of motion of the model of FIG. 5 is given by

と定義し、状態空間表示すると次式となる。

In the above equations (1) and (2), the state variable X and the control input u are respectively

When the state space is displayed, the following equation is obtained.

を最小にする制御入力ｕは、次式の状態フィードバックで与えられる。

ここで、Ｑ及びｒは、状態変数にかかる重み行列、制御入力に係る重み係数である。又、Ｐはリカッチ方程式の解である。 Therefore, a control system is designed for the above equation (3). For example, LQ control theory is applied to the control system. According to the LQ control theory, the weight function J,

The control input u that minimizes is given by the state feedback of the following equation.

Here, Q and r are a weighting matrix related to the state variable and a weighting coefficient related to the control input. P is the solution of the Riccati equation.

FIG. 6 shows the calculation result. The mass ratio of m ₁ and m ₂ is 1.0, and the time history response waveform when a forcing force of sine wave f = Fsin (ωt) is input to m ₂ is shown. Line a is a tower structure The absolute displacement of the support frame 4 that swings together with the main body 2, the line b indicates the relative displacement of the residential area 3 with respect to the support frame 4, and the line c indicates the absolute displacement of the residential area 3.

  As is clear from FIG. 6 above, the relative displacement of the residential area 3 with respect to the support frame 4 is set to have the same amplitude and opposite phase with respect to the absolute displacement of the support frame 4 that swings together with the tower-like structure body 2. It can be seen that the displacement of the residential area 3 in the absolute space, that is, the shaking of the residential area 3 can be reduced.

  Therefore, in the controller 7, when the swing of the support frame 4 that swings together with the swing of the tower-like structure body 2 is detected by the acceleration sensor 6 and inputted, the actuators 5a and 5b are input. On the other hand, a control command is given so that the residential area 3 is relatively displaced with the same amplitude and opposite phase as the absolute displacement of the support frame 4 with respect to the support frame 4.

  According to the vibration isolator in the structure living area having the above configuration, when the tower-like structure body 2 starts to shake due to external force such as wind external force, the support frame 4 that shakes together with the tower-like structure body 2 is supported. A control command is given to the actuators 5a and 5b from the controller 7 based on a signal input from the acceleration sensor 6 provided to the controller 7 to the support frame. 4, the residential area 3 is relatively displaced with the same amplitude and opposite phase as the absolute displacement of the support frame 4, so that the absolute displacement of the residential area 3 is suppressed. Therefore, regardless of the shaking of the tower-like structure body 2, the shaking of the residential area 3 is greatly reduced.

  As described above, according to the vibration isolation method and apparatus for a structure residential area of the present invention, any vibration may occur in the tower-shaped structure body 2 by vibration-insulating the residential area 3 from the tower-shaped structure body 2. In both cases, the shaking of the residential area 3 can be suppressed, and the people in the residential area 3 can be protected from shaking.

  Moreover, the residential area 3 is moved up and down along the tower-like structure body 2 together with the support frame 4, so that the residential area 3 is arranged at any of the upper part, the middle part, and the lower part of the tower-like structure body 2. Even in the above state, the support frames 4 arranged on the upper, middle and lower parts of the tower-like structure body 2 together with the living area 3 sway in the upper, middle and lower parts of the tower-like structure body 2. Since the residential area 3 can be relatively displaced on the support frame 4 so as to cancel out the absolute displacement of the support frame 4 when swaying according to the Regardless of the height position, it is possible to reliably suppress the shaking of the residential area 3 without changing or adjusting the device configuration.

  Furthermore, a mass damper system damping device for reducing the shaking of the tower-like structure 1 itself can be made unnecessary.

  The present invention is not limited only to the above embodiment, and the control law of the actuators 5a and 5b by the controller 7 is simpler by preventing the direct influence of the wind force on the residential area 3. From the point of view, it is preferable to provide the outer peripheral frame 20 that covers the outer peripheral side of the residential area 3 and the ceiling frame 21 that covers the upper part of the residential area 3, but the outer peripheral frame 20 and the ceiling frame 21 as shown in FIG. The configuration may be omitted. In this case, in consideration of the force acting on the residential area 3 by the direct action of the wind force on the residential area 3, the displacement response in the absolute space of the residential area 3 is reduced. The control law of the actuators 5a and 5b by the controller 7 may be derived.

  Further, as described above, when the outer peripheral frame 20 and the ceiling frame 21 are omitted, the support frame 4 can support the residential area 3 so as to be displaceable in all directions and is interposed between the residential area 3 and the actuator 5a. , 5b and the acceleration sensor 6 can be installed, the outer peripheral side end of the support frame 4 does not necessarily have to protrude to the outer peripheral side of the living area 3. Therefore, the shape of the outer peripheral side end of the support frame 4 may be changed as appropriate. Furthermore, in this case, the inner peripheral frame 4 a attached to the inner peripheral end of the support frame 4 may have an upper end lower than the upper end of the living area 3.

  Moreover, in the said embodiment, although it showed about what was applied to the tower-like structure 1 of the type with which the residential area 3 was attached to the tower-like structure main body 2 so that raising / lowering was possible, as shown in FIG. A support frame 4 similar to that of the embodiment of FIGS. 1 to 6 is fixed at a required height position of the structure main body 2, and similarly to the embodiment of FIGS. 1 to 6 above the support frame 4. The residential area 3 is supported so as to be displaceable in all directions within a horizontal plane, and an actuator 5 is provided between the support frame 2 and the residential area 3, and the support is supported by driving the actuator 5. The residential area 3 can be moved relative to all directions in the horizontal plane on the frame 2, and the acceleration sensor 6 for detecting the shaking of the support frame 4, and the input signal from the sensor 6 According to the above actuator 5 may be configured comprising a control unit 7 which gives a control command to.

  The control law for controlling the actuators 5a and 5b by the controller 7 is based on a control theory other than the LQ control theory as long as the response of the displacement in the absolute space of the residential area 3 can be reduced. It may be derived.

  An acceleration sensor 6 is shown as a sensor for detecting the shaking of the support frame 4, and the relative displacement direction, displacement amount, and displacement speed of the residential area 3 on the support frame 4 are determined by the actuators 5 a and 5 b. Although shown as what is detected from the number of rotations of the drive motor 17, if it is possible to detect the shaking of the support frame and the relative displacement direction, displacement amount, and displacement speed of the residential area 3 on the support frame 4, respectively. Any sensor may be employed.

    The lifting / lowering driving mechanism 10 of the support frame 4 in the embodiment of FIGS. 1 to 4 may adopt a rack / pinion type or any other type of lifting / lowering driving mechanism other than those illustrated.

  The tower-like structure body 2 may be provided with a mass damper system for quickly reducing the shaking generated in the tower-like structure body 2 or any other type of vibration damping device. In addition, when higher-order mode vibration occurs in the tower-like structure body 2, a mass damper method or any other method of vibration damping is provided at the center in the height direction of the tower-like structure body 2 that becomes the antinode of the mode. An apparatus may be provided.
