Description
Technical field
The utility model belongs to civil engineering structure antivibration area, is specifically related to a kind of for controlling the tuning mass bumper of building structure low frequency vibration.
Background technology
Development along with urban construction, various high levels, super highrise building and thin and tall structure, long span building thing are increasing, the realistic problem of having to address in becoming engineering construction in this class large span of control, the destructive resonance of low frequency configuration thing generation, facts have proved, tuning mass bumper (also has and in document, claims tuned mass damper, tuned mass damper or claim mass tuning damper, also be called for short TMD herein) be a kind of effective vibration control apparatus, its intrinsic frequency is adjusted to the natural frequency that approaches structure, then installed structurally.When structure is subject to exciting force interference generation vibration, cause the resonance of mass tuning damper, utilize the vibrating inertia force of tuning quality to react on structure itself, thereby offset exciting force, reach the object that reduces structural response.Want to bring into play to greatest extent the damping effect of mass tuning damper, require its intrinsic frequency consistent with the natural frequency of main structure as far as possible, otherwise the effectiveness in vibration suppression of TMD will decline to a great extent.Because the mass of tuning mass bumper is big or small and proportional by the gross weight of vibration-proof structure, for heavy construction structures such as skyscraper, its quality is huge, required TMD quality is generally all at hundreds of tons, the spring cost of high rigidity is high, manufacture and be difficult for, therefore this type of large-scale TMD substantially adopts pendulum-type structure at present, and the utility model patent that for example application number is 201310080464.3 discloses a kind of like this pendulum-type eddy current tuned mass damper device.
According to theoretical mechanics general knowledge, the intrinsic frequency of this type of pendulum-type tuning mass bumper and the relation of pendulum length as shown in Equation (1):

| f(Hz) | L(m) |
| 0.5 | 0.993955 |
| 0.4 | 1.553055 |
| 0.3 | 2.760986 |
| 0.2 | 6.21222 |
| 0.15 | 11.04395 |
| 0.1 | 24.84888 |
| 0.05 | 99.39551 |
As seen from the above table, existing pendulum-type tuning mass bumper is unsuitable for controlling intrinsic frequency lower than the low frequency vibration of 0.15Hz, is mainly because required pendulum length is excessive, need to take too many installing space, applicability is poor, in real engineering, substantially all cannot meet so large space requirement.
