Description

Damping system

The present invention relates to a shock absorbing system, and more particularly to a shock absorbing system for damping by a weight coordinated damper and a liquid coordinated damper.

When the offshore floating platform (for example, oil rig or large oil tanker) is operated at sea, it may be affected by waves and vibrate or shake, which may cause the operation to be interrupted. In order to reduce the vibration caused by the floating platform at sea, The impact is necessary to set up a facility for reducing vibrations at the floating platform.

Please refer to FIG. 1 , for example, the invention patent of No. 400297 “Floating Barge Platform and Assembly Method” of the Republic of China, discloses a conventional damping system 9 which is connected by a plurality of modules 91 to form a barge platform. An opening 92 is formed in the center of the conventional damping system 9, and a plurality of damping plates 93 are disposed around the outer sides of the modules 91. Therefore, the depth of the draft of the conventional shock absorbing system 9 can be increased by the opening 92, so that the conventional shock absorbing system 9 reduces the actual bottom area affected by the wave, and the damper plate 93 is used to mitigate the wave pair conventionally. The role of the earthquake system 9.

However, the conventional shock absorbing system 9 is only damped by the opening 92 and the damper plate 93. When the wave strength is large, the shock absorbing effect is not good, and the opening 92 and the damper plate 93 of the conventional damper system 9 are It is impossible to adjust according to the wave period. Therefore, the conventional damping system 9 cannot adjust the damping effect in response to characteristics such as the above-described wave period.

In addition, due to the limited land area in the city, in order to increase the use of space, the height of the building continues to rise. For areas where the plate is at the junction (for example, Taiwan and Japan, etc.), the number of earthquakes is quite frequent. In addition to strengthening the structural safety of the building itself, how to influence the impact of the earthquake (for example: about life and It is an urgent task to minimize property security.

Please refer to FIG. 2, such as the invention patent of "Isolation Isolator" of the Republic of China No. I306137, which discloses a conventional shock absorbing system 8 which is disposed opposite to a base 82 by a top seat 81. The bottom surface is recessed to form an arc-shaped top sliding slot 811. The top surface of the base 82 is recessed to form an arc-shaped base sliding slot 821. The top sliding slot 811 and the base sliding slot 821 are slidably disposed with a sliding plate 83, respectively. A sliding joint device 84 is disposed between the two slide plates 83. At least one of the top seat 81, the base 82 and the sliding joint device 84 is provided with a damping device 85. Therefore, after the top sliding slot 911 and the base sliding slot 821 slide, the sliding joint device 84 can be reset by the two sliding plates 83 to cause the base 82 to move horizontally relative to the top seat 81 when vibrating. And the vibration energy is transmitted in the horizontal direction, and the damping device 85 is used to absorb the vibration energy transmitted in the horizontal and vertical directions, thereby achieving the effects of effective shock absorption and isolation.

However, the conventional shock absorbing system 8 needs to couple the base 82 to the ground (ie, the source transfer object) when the building starts construction, and combine the top seat 81 with the building foundation (ie, the shock absorbing object) to borrow The sliding connection device 84 and the damper device 85 are damped, and once the building has been completed, the conventional damper system 8 cannot be used as the damper device.

In summary, it is necessary to provide a shock absorbing system that not only adjusts the shock absorption effect in response to the wave period, but is also suitable for installation in various types of completed buildings.

It is an object of the present invention to improve the above-discussed shortcomings to provide a shock absorbing system that adjusts the shock absorbing effect with the wave period by adjusting the weight of the shock absorbing system.

A second object of the present invention is to provide a shock absorbing system that is not required to be disposed between a source transmitting object and a shock absorbing object, but is suitable for being installed in various types of completed buildings.

A shock absorption system includes: a base comprising a casing, a first chamber, a second chamber, a translation unit, an elastic member, a damper and a liquid, the interior of the housing Forming the first chamber and the second chamber, the translating unit is translatably disposed in the first chamber, the elastic member and the damper are coupled between the housing and the translating unit, the liquid capacity Positioned in the second chamber; and a control module is provided with a liquid amount adjusting component and a processing unit, the liquid amount adjusting component is connected to the translation unit of the base and the second chamber, and the processing unit is electrically Connect the liquid volume adjustment assembly.

The above and other objects, features and advantages of the present invention will become more <RTIgt;

The "Tuned Mass Damper" (TMD) as used throughout the present invention refers to a device capable of effectively suppressing the movement of a structure at a specific applied frequency after being subjected to an external force. It will be understood by those of ordinary skill in the art to which the present invention pertains.

The "Tuned Liquid Damper" (TLD) as used throughout the present invention refers to a device capable of effectively suppressing the movement of a structure under the action of a liquid after being subjected to an external force. It will be understood by those of ordinary skill in the art to which the present invention pertains.

The "Liquid-Sloshing Force" as used throughout the present invention means that when a container (for example, a sink float) is subjected to an external force, liquid-sloshing occurs in the liquid in the container. The force of reciprocating oscillating forces within the container is understood by those of ordinary skill in the art to which the present invention pertains.

"Non-Sloshing Liquid" as used throughout the present invention means that when the chamber of the weight-type coordinated damper contains liquid, the volume of the chamber can be calculated and changed to the volume of the liquid. Therefore, when the wave energy is applied to the weight coordinated damper, the liquid cannot be oscillated due to the state in which the liquid remains filled in the chamber, as will be understood by those of ordinary skill in the art to which the present invention pertains.

The "sloshing liquid" as used throughout the present invention means that when the chamber of the liquid coordinated damper contains liquid, the volume of the chamber is larger than the volume of the liquid, that is, the chamber contains free space, therefore, When the wave energy is applied to the liquid coordinated damper, it is understood by those of ordinary skill in the art that the free space allows the liquid to change shape so that the liquid can oscillate in the chamber.

Please refer to FIG. 3 , which is a schematic diagram of a system of a first embodiment of the shock absorption system of the present invention, which comprises a base 1 and a control module 2 . The pedestal 1 is provided with the control module 2, and when the pedestal 1 floats on the sea surface W, it can serve as an offshore platform, and the wave information is obtained by the control module 2. The shock absorption effect is generated in response to the wave period.

The base 1 includes a casing 11, a first chamber 12, a second chamber 13, a translation unit 14, an elastic member 15, a damper 16, and a liquid 17, and the housing 11 is A hollow object having a rigid structure is formed, for example, a floating tank capable of carrying weight and resisting wave breaking force, so that the casing 11 can float on the sea surface W and be driven by wave energy on the sea surface W. For example: surge or heave. The interior of the housing 11 forms the first chamber 12 and the second chamber 13; the translating unit 14 is composed of a weight coordinated damper (TMD), such as an object having a pulley or a slide rail, etc., the structure thereof It will be understood by those skilled in the art that, as will be described herein, the translating unit 14 is translatably disposed inside the housing 11 such that the wave energy applied to the base 1 is eliminated; the elastic member 15 is combined. When the housing 11 is forced to swing between the inner wall surface of the housing 11 and the translating unit 14, the translating unit 14 can linearly reciprocate; the damper 16 is coupled to the inner wall surface of the housing 11 and The damper 16 can slow the moving speed of the translating unit 14 when the housing 11 is forced to swing between the translating units 14; the liquid 17 is accommodated in the second chamber 13 to form a liquid coordination A damper (TLD), when the liquid 17 is swayed by control (such as the oscillating liquid L _S shown in FIG. 3 ), offsets the external force of the susceptor 1 and reduces the swing of the pedestal 1 Amplitude. The base 1 can also be provided with a fixing assembly 18 comprising a plurality of cables 181 (for example made of PE, nylon or high modulus material) and a plurality of anchors 182 (for example One end of each of the cables 181 is coupled to the base 1, and the other end of each of the cables 181 is coupled to the anchor body 182, and the anchor body 182 is fixed to the seabed B. The fixing assembly 18 The connection method is familiar to those skilled in the art and will not be described here. The embodiments are exemplified herein as follows, but are not limited thereto.

For example, the interior of the housing 11 of the base 1 is formed by a spacer 11a forming the first chamber 12 and the second chamber 13. The translation unit 14 is a square object having a pulley as an embodiment. The first chamber 12 is disposed in the first chamber 12 and is translatably disposed on the spacer 11a, and the translating unit 14 is provided with a chamber 141 for accommodating liquid such as seawater and keeping the liquid from swinging (Sloshing). A non-sloshing liquid L _{N is formed} to increase the weight of the translating unit 14. The elastic member 15 and the damper 16 are coupled between the housing 11 and the translating unit 14. The stiffness or Elasticity of the elastic member 15 is positively correlated with the displacement of the translation unit 14. The liquid 17 is accommodated in the second chamber 13 to form a liquid coordinated damper (TLD). When the liquid 17 is swayed by control, a coupling effect is generated between the liquid and the casing 11. And a new characteristic frequency (Eigenfrequency) is formed, and it can be known from the conventional physical knowledge that when the period of the characteristic frequency is the same as the frequency of the Ocean Wave, if the phase is different or opposite, the weight is made. The coordinated damper can eliminate the energy of the external force, and the liquid coordinated damper can cancel the external force, so that the displacement of the pedestal 1 is reduced, and the shock absorbing effect is generated. Wherein, the capacity or weight of the liquid 17 is positively correlated with the total weight of the susceptor 1, and is positively correlated with the weight ratio of the translating unit 14 and the liquid 17, and the total weight or the weight ratio is positively correlated with the characteristic frequency. And phase control is not the focus of discussion in this case, so I won't go into details here.

The control module 2 is disposed on the housing 11 of the base 1 and is preferably disposed inside the housing 11 to prevent the control module 2 from being damaged by wave impact. The control module 2 comprises a liquid amount adjusting component 21 and a processing unit 22, and the liquid amount adjusting component 21 is composed of a device having a liquid conveying function, for example, a pump is connected by a pump (Pipe). And the liquid amount adjusting component 21 is connected to the translating unit 14 of the base 1 for adjusting the liquid capacity (or weight) of the translating unit 14. The liquid adjusting component 21 is arranged in a manner familiar to the skilled person. Understand, I will not repeat them here. The processing unit 22 is composed of a device having a wireless communication and numerical calculation function, for example, a microprocessor (Micro-processor) having a wireless communication transceiver (Chip), for storing programs and receiving "sea weather observation". Radio waves of instruments (eg, floating stations at sea, submarine wave stations, and offshore observation piles, etc.) to know the wave period of the location of the pedestal 1, and to optimize the damping efficiency according to the wave period. That is, the weight of the translation unit 14 of the susceptor 1 is calculated. The processing unit 22 is electrically connected to the liquid amount adjusting component 21, and adjusts information according to the calculated weight and the like, and sends a signal to drive the liquid amount adjusting component 21 so that the liquid amount adjusting component 21 can adjust the base 1 The liquid capacity enables the weight-type coordinated damper to eliminate the energy of the external force, and the liquid-type coordinated damper can cancel the external force, so that the displacement of the susceptor 1 is reduced, and the shock absorbing effect is produced. The embodiments are exemplified herein as follows, but are not limited thereto.

For example, as shown in FIG. 3, the control module 2 is disposed inside the casing 11 of the base 1, and the liquid amount adjusting component 21 is connected by a pump to a plurality of conduits (for example, 3 conduits). ), wherein two conduits communicate with the base 1 The chamber 141 of the translating unit 14 and the second chamber 13 are connected to the outside of the housing 11 of the base 1; the processing unit 22 performs the optimization of the damping efficiency according to the wave period, and then sends out the signal. Driving the pump to extract seawater to the chamber 141 of the translating unit 14, the second chamber 13, or discharging the seawater in the chamber 141 and the second chamber 13 from the shell of the base 1. The body 11 enables the weight-type coordinated damper to eliminate the energy of the external force, and the liquid-type coordinated damper can cancel the external force, so that the displacement of the susceptor 1 is reduced, and the shock absorbing effect is produced.

When the damping system of the present invention is used, the control module 2 receives the wireless signal of the sea meteorological observation instrument, and reads the wave period of the position of the base 1; and then the control module 2 according to the base The weight of the translation unit 14 and the liquid 17 is calculated by the wave period of the position; then, the weight of the translation unit 14 and the liquid 17 is adjusted by the control module 3. In detail, the control module 2 receives the radio waves of the "sea meteorological observation instrument" for interpreting the wave period of the position of the susceptor 1 and storing the wave period. Then, since the weight of the liquid of the translating unit 14 and the second chamber 13 changes, the natural vibration frequency of the shock absorbing system will be changed, and when the damping system and the external force cause a decrease in the resultant force, This causes the displacement amount of the susceptor 1 to become small, and the effect of damping is generated. Therefore, the control module 2 calculates the weight ratio of the liquid of the translation unit 14 and the liquid 17 of the second chamber 13 according to the change of the wave period of the position of the susceptor 1 , and converts the weight ratio of the liquid 17 of the second unit 13 to the translation unit 14 . The liquid and the liquid of the second chamber 13 and the weight of the shock absorbing system allow the susceptor 1 to produce a reduced amount of displacement.

More specifically, since a liquid coordinated damper is formed in the susceptor 1 Coupling will occur, and a new characteristic period (Eigenfrequency) will be generated, and the weight ratio of the liquid of the translating unit 14 and the liquid of the second chamber 13 will change the natural vibration frequency when the pedestal 1 When moving, the water level of the liquid 17 in the second chamber 13 will start to oscillate, and the water level symmetry is formed on the opposite wall surfaces of the second chambers 13, and the liquid 17 will generate broken waves and consume external force. The energy, therefore, when the combined force of the liquid oscillating force and the external force generated by the susceptor 1 is reduced, the displacement amount of the susceptor 1 is reduced.

For example, when the external force period changes, the total weight of the damping system also needs to be changed. Therefore, the control module 2 can calculate the ratio of the swing frequency (ω _f ) of the liquid 17 to the external force frequency (ω _e ). And the ratio of the natural resonance frequency (ω _s ) of the damping system to the external force frequency (ω _e ), and the difference between the value of the external force period and (ω _s /ω _e )=1 is calculated when the external force period fluctuates. The natural resonance frequency (ω ₂ ) of the seismic system, and calculate the total weight value of the damping system at the optimum weight ratio, and then calculate the depth and capacity of the liquid 17 by using the relationship of (ω _f /ω _e )<0.9. The weight and the like make the shock absorption system achieve the best shock absorption effect.

In addition, since the pedestal 1 floats on the sea surface W, if the weight of the translation unit 14 and the liquid 17 is changed in response to the wave period, the control module 3 can pump seawater into/out of the translation unit 14. The chamber 141 and the second chamber 13 change the weight of the translating unit 14 and/or the liquid 17, further reducing the displacement of the damping system. Among them, the shock absorbing system of the present invention can be used not only as an offshore platform having a shock absorbing effect but also as a land building that has been constructed.

Please refer to FIG. 4, which is the second embodiment of the shock absorption system of the present invention. A schematic diagram of a system in which the damping system is disposed on a floor G of a building A. The base 1 is provided with the control module 2, and the base 1 does not need to be provided with the fixing component of the first embodiment. When the base 1 is placed on the floor G, the shock absorption effect can be generated according to the shock period.

In detail, the control module 2 receives the radio wave of the "seismic observation instrument" for interpreting the seismic wave period of the position of the susceptor 1 and storing the seismic wave period. Then, since the weight of the liquid of the translating unit 14 and the second chamber 13 changes, the natural vibration frequency of the damping system is changed, and the period and the seismic wave converted by the natural vibration frequency of the damping system are changed. When the cycle is the same and the phase is different, the liquid coordinated damper will cancel the external force generated by the earthquake, and the resultant force will decrease. The weight coordinated damper can destroy the energy generated by the earthquake, resulting in the displacement of the pedestal 1. Small, and the building A has a shock absorption effect. Therefore, the control module 2 calculates the weight ratio of the liquid of the translation unit 14 and the liquid 17 of the second chamber 13 according to the change of the seismic period of the position of the susceptor 1, and converts the weight ratio of the liquid 17 to the translation unit 14 The liquid and the liquid of the second chamber 13 and the weight of the shock absorbing system enable the base 1 to reduce the amount of displacement, thereby causing the building A to have a shock absorbing effect.

The main feature of the shock absorption system of the present invention is that a liquid coordinated damper is formed in the base 1 by the technical means disclosed above. When the base 1 and the liquid coordinated damper are coupled with the same period and wave period, When the phases are different, the displacement amount of the susceptor 1 can be reduced, and the susceptor 1 can be damped. Therefore, when the wave period is changed, the weight of the weight coordinated damper and the liquid coordinated damper corresponding to the wave period can be calculated by the control module 2 for adjusting the translation unit 14 and the second chamber. 13 The liquid capacity allows the damping system to maintain optimum shock absorption. Therefore, the damping system of the present invention can achieve the effect of adjusting the damping effect with the wave period by adjusting the weight of the damping system.

Furthermore, since the damper system of the present invention is disposed on the floor G of the building A, that is, not disposed between the source transmitting object and the damper object, if the building has been completed, the present invention can of course be used. The shock absorbing system of the invention is used as a shock absorbing device. Therefore, the shock absorbing system of the present invention has an effect suitable for being installed in various types of constructed buildings.

While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention. The technical scope of the invention is protected, and therefore the scope of the invention is defined by the scope of the appended claims.
