Description

Technical Field

[0002] A tuned mass damper (TMD), also known as a tuned mass damper, is a vibration control device commonly used in tall buildings, bridges, and other large structures.

[0003] The TMD system adds an inertial mass to the top floor of the building structure and is equipped with a spring system and a damping system. Through the principle of resonance, a certain vibration mode of the structure is controlled to achieve the effect of vibration reduction. The TMD system can effectively reduce the vibration response of the main structure and has a significant control effect on the vibration of the structure. Therefore, the main structure can reduce the cross-sectional size of the components, reduce the reinforcement, simplify the construction, and significantly save the cost of the structural engineering; it occupies very little building area and is easy to install, repair and replace; it can make full use of the existing structure of the main structure for TMD, and there is no need to set up a special tuning device; the use of TMD provides an alternative vibration reduction measure for some structures that are difficult to adopt traditional reinforcement measures, such as high-rise structures, high-rise tower structures, large-span structures, offshore platforms and other major structures; the frequency-tuned mass damper has broad application prospects in the seismic and wind resistance control of high-rise and tall structures.

[0019] (3) Beneficial effects

[0020] A. The slide rail supported frequency modulated mass damper is provided with a horizontal slide rail support assembly. When the structural building is subjected to wind vibration or earthquake, the main body of the frequency modulated mass damper is subjected to force to drive the slide seat to slide horizontally along the slide groove on the base. During the process, the arc spring plate in the sliding direction of the slide seat is subjected to force to deform and expand. During the deformation process of the arc spring plate, the two ends will drive the slider to move horizontally along the slide rail groove. The guide block at the bottom of the slider is engaged and inserted into the guide groove at the bottom of the slide rail groove to prevent the slider from leaving the slide rail groove and to prevent the two ends of the arc spring plate from derailing. During the horizontal sliding process of the main body of the frequency modulated mass damper, the arc spring plate is driven to deform and consume energy, thereby effectively controlling the wind vibration and earthquake effects in all horizontal directions.

[0021] B. Through the arrangement of the horizontal slide rail support assembly and the linkage air injection dust blowing assembly, during the horizontal vibration damping process of the above-mentioned slide rail support type frequency modulation mass damper, the deformation of the arc spring plate drives the sliders at both ends to move horizontally along the slide rail groove, and the slider drives the first piston to move back and forth in the first cylinder tube through the first connecting rod. The suction force generated by the movement of the first piston in the first cylinder tube is sucked through the suction pipe. Under the unidirectional transmission action of the first one-way valve, the sucked air is continuously input into the airbag sealing ring through the air supply branch pipe, and the airbag sealing ring is inflated and expanded in the sliding groove to press against the outer wall of the slide seat. The air bag seal ring is continuously injected with air. When the air pressure in the air bag seal ring reaches the threshold of the pressure relief valve, the excess air is input into the annular tube through the air delivery branch pipe and blown out at each blowing head to blow dust from the covering gap between the air bag seal ring and the slide seat to prevent dust and impurities from invading the slide groove, thereby ensuring the smooth sliding of the slide seat in the slide groove.

[0022] C. Through the setting of the guide lubrication component, the main body of the frequency-modulated mass damper will resist and push the resistance block on one side during the lateral movement, and the second piston will be driven to move in the second tube through the second connecting rod. The holding spring will be compressed during the process, and the second piston will be driven to reset under the action of the holding spring. The second piston moves back and forth in the second tube, and the suction force generated by the second one-way valve sucks the lubricating oil in the sliding groove through the suction pipe, and inputs it into the ring pipe through the infusion main pipe. The lubricating oil is also input into the oil collecting ring through each injection branch pipe. The lubricating oil pump is filled into the oil collecting ring to play the role of lubricating the guide column in the basic frequency-modulated mass damper structure.

Under the unidirectional transmission effect of the first one-way valve 706, the sucked air is continuously input into the airbag sealing ring 6 through the air supply branch pipe 707. The airbag sealing ring 6 is inflated and expanded in the sliding groove 502 to cover the outer wall of the sliding seat 501, so that a closed oil storage space is formed in the sliding groove 502, which is conducive to sliding.

[0048] Working principle: When the present invention is in use, during the use of the slide rail supported frequency modulation mass damper, when the structural building is subjected to wind vibration or earthquake, the frequency modulation mass damper body 1 is forced to drive the slide seat 501 to slide horizontally along the slide groove 502 on the base 2. During the process, the circular arc spring plate 508 in the sliding direction of the slide seat 501 is forced to deform and expand. During the deformation process of the circular arc spring plate 508, the two ends will drive the slider 504 to move horizontally along the slide rail groove 503. The guide block 505 at the bottom of the slider 504 is engaged and inserted into the guide groove 506 at the bottom of the slide rail groove 503 to prevent the slider 504 from detaching from the slide rail groove 503 and to prevent the two ends of the circular arc spring plate 508 from derailing. During the horizontal sliding process of the frequency modulation mass damper body 1, The moving circular arc spring plate 508 generates deformation energy consumption, thereby being able to effectively control the wind vibration and earthquake effects in all horizontal directions.

The deformation of the circular arc spring plate 508 drives the sliders 504 at both ends to move horizontally along the sliding rail groove 503. The slider 504 will drive the first piston 702 to move back and forth in the first tube 701 through the first connecting rod 703. The suction force generated by the movement of the first piston 702 in the first tube 701 is sucked through the suction pipe 704. Under the unidirectional transmission effect of the first one-way valve 706, the sucked air is continuously input into the airbag sealing ring 6 through the air supply branch pipe 707. The airbag sealing ring 6 The air is inflated and expanded in the sliding groove 502 to cover the outer wall of the slide seat 501, so that a closed oil storage space is formed in the sliding groove 502, which is beneficial to the storage of lubricating oil in the sliding groove 502. The flexible structure of the airbag sealing ring 6 does not affect the horizontal sliding of the slide seat 501 along the sliding groove 502. When the air pressure in the airbag sealing ring 6 reaches the threshold of the pressure relief valve 710, the excess air is input into the annular tube 708 through the air delivery branch pipe 707 and blown out at each blowing head 709, and dust is blown from the covering gap between the airbag sealing ring 6 and the slide seat 501 to prevent dust and impurities from invading the sliding groove 502, thereby ensuring that the slide seat 501 in the sliding groove 502 slides smoothly. The resistance block 806 on one side resists and pushes, and drives the second piston 804 to move in the second tube 802 through the second connecting rod 805.

The second piston 804 reciprocates in the second tube 802, and the suction force generated by the second one-way valve 809 sucks the lubricating oil in the sliding groove 502 through the suction pipe 807, and is input into the ring pipe 811 through the infusion main pipe 808.
