Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Refer to Fig. 1-3, a kind of tuned mass damper, TMD, including tuning quality block 1, spring damping vibration isolator 2, adjusting bolt 3, panel, connecting rod 6 and attaching nut 7, described panel includes top panel 4 and lower panel 5, the quantity of spring damping vibration isolator 2 is two or more and the two ends being symmetrically installed on lower panel 5 top, spring damping vibration isolator 2 top is provided with top panel 4, spring damping vibration isolator is connected with top panel 4 by adjusting bolt 3, top panel 4 top is provided with tuning quality block 1, connecting rod 6 runs through tuning quality block 1, top panel 4 and lower panel 5, connecting rod 6 is provided with attaching nut 7, spring damping vibration isolator 2 includes locking nut 21, upper shell 22, piston 23, viscous damping 24, spring 25 and lower house 26, piston 23 is fixed on upper shell 22 by locking nut 21, the lower end of piston 23 is connected with viscous damping 24, viscous damping 24 is arranged on lower house 26 upper end, spring 25 it is wound with between upper shell 22 and lower house 26. the quantity of connecting rod 6 is two, and in each spring damping vibration isolator 2, the quantity of adjusting bolt 3 is three. three adjusting bolt 3 distributions in equilateral triangle on spring damping vibration isolator 2. being provided with T-slot in lower panel 5, spring damping vibration isolator 2 is arranged in T-slot. adjusting bolt nut it is provided with between adjusting bolt 3 and top panel 4. piston 23 be shaped as tubulose, bar-shaped, rectangle or tabular, in each spring damping vibration isolator 2, the quantity of piston 23 is more than one. tuning quality block 1 adopts plurality of steel plates to form.
Operation principle of the present utility model is: if frequency and damping ratio adjusting range are less, frequency is adjusted by adding and subtracting the weight of tuning quality block 1, by adjusting the size of the area that piston 23 is immersed in viscous damping 24, thus the size changing damping reaches the requirement of reality.When damping turned down by needs, unclamping adjusting bolt nut, adjusting bolt 3 is adjusted up, and is upwards slowly pulled up by piston 23, so makes the contact area that piston 23 is immersed in viscous damping 24 reduce, and corresponding damping is reduced by; When needs tune up damping, unclamping adjusting bolt nut, adjusting bolt 3 regulates downwards, is then moved down by piston 23, so makes the contact area that piston 23 is immersed in viscous damping 24 increase, and corresponding damping is increased by. If frequency and damping ratio adjusting range are relatively big, realize by changing the spring damping vibration isolator 2 of coupling. When needing to change spring damping vibration isolator 2, unclamp adjusting bolt nut and locking nut 21, place four little jack herein above between plate 4 and lower panel 5 and jacking to the spring 25 of spring damping vibration isolator 2 no longer carry, because lower panel 5 has T-slot, two side shiftings can take out spring damping vibration isolator 2 to the left and right respectively, then new spring damping vibration isolator 2 is installed, release jack, locking locking nut 21, if needing frequency and damping ratio are finely tuned the step repeating damping adjusting. This apparatus structure is simple, reasonable in design, failure rate is low, good operation stability; This device detachability is good, it is simple to installs and changes; This device can according to practical situation, by adjust the weight of tuning quality block 1, damping adjusting size and change spring damping vibration isolator adjust frequency and damping ratio, result of use is good, and the spring damping vibration isolator under changing can reuse, it is to avoid the wasting of resources.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, it is also possible to make a variety of changes under the premise without departing from this patent objective.
