Steel wire rope damper and vibration reduction device for cable structure
The invention relates to a steel wire rope damper for a cable structure and a vibration reduction device. The steel wire rope damper achieves energy consumption of vibration of the cable structure through a steel wire rope, has a good restraining effect on high-frequency vibration of the cable structure and has a certain restraining effect on low-frequency vibration of the cable structure. A first permanent magnet type magnetic stiffness element and/or a second permanent magnet type magnetic stiffness element are/is arranged between the two clamping plate groups of at least one clamping plate unit, and the first permanent magnet type magnetic stiffness element utilizes the magnetic force of the two corresponding permanent magnets; the second permanent magnet type magnetic stiffness element utilizes the magnetic force of the two corresponding permanent magnets to eliminate the reduction effect of the self-stiffness of the steel wire rope damper on the vibration damping performance of the cable structure when the steel wire rope damper is compressed, and the second permanent magnet type magnetic stiffness element utilizes the magnetic force of the two corresponding permanent magnets to eliminate the reduction effect of the self-stiffness of the steel wire rope damper on the vibration damping performance of the cable structure when the steel wire rope damper is stretched. The control effect of the steel wire rope damper on vibration of the cable structure is improved, and the steel wire rope damper can meet the higher requirement for vibration reduction of the cable structure.
本发明涉及一种用于索结构的钢丝绳阻尼器及减振装置。钢丝绳阻尼器，通过钢丝绳实现对索结构振动的耗能，其对索结构的高频振动具有很好的抑制作用，对索结构的低频振动具有一定的抑制作用；且通过在至少一个所述夹板单元的两个夹板组之间设有第一永磁体式磁刚度元件和/或第二永磁体式磁刚度元件，第一永磁体式磁刚度元件利用对应两个所述永磁体的磁力，可以消除钢丝绳阻尼器压缩时自身刚度对索结构振动减振性能的折减效果，第二永磁体式磁刚度元件利用对应两个所述永磁体的磁力，能够消除钢丝绳阻尼器拉伸时自身刚度对索结构振动减振性能的折减效果，提高对钢丝绳阻尼器对索结构振动的控制效果，使得钢丝绳阻尼器能满足更高需求的索结构减振。
