Technical field
The present invention relates to a kind of damping controller for suspended tuning mass damper, especially a kind ofly can avoid balancing weight to reverse and shake, and can use for a long time and the damping control device that need not to keep in repair, can be used for the vibration damping control of tower building structure etc.
Background technology
Damping controller for suspended tuning mass damper (Tuned Mass Damper, be called for short TMD) be installed in the building structure, utilize resonance principle, the vibrational energy absorption of agent structure is transferred on the control device, thereby the wind that reduces building structure shakes and earthquake response, international and domestic more application has been arranged.Computational analysis and facts have proved, when the TMD quality is suitable, the frequency of TMD control device and agent structure frequency are approaching, and the damping ratio of TMD is between 3-7% the time, and the vibrational energy of controlled building structure is farthest transferred on the TMD control device.Under the TMD of optimum device control parameters (quality that comprises TMD, frequency and damping), the TMD device can reduce that main body controlled structures wind shakes and earthquake response reaches more than the 40-50%, and vibration damping control effect is very considerable.
At present, existing suspension TMD damping control device is mainly by balancing weight, and messenger wire and damper are formed, as shown in Figure 1.Balancing weight 3 is suspended on the agent structure 1 by messenger wire 2, and piston type damper 4 and spring assembly 5 are set between balancing weight and the structure.There are the following problems for existing suspension TMD damping control device: (1) only uses the balancing weight of messenger wire (being generally steel strand) suspention to occur easily reversing and shake up and down, has influenced control stability; (2) damping unit of existing suspension TMD damping control device adopts the piston type damper more, not only can not revise damping parameter after machining, and have more serious problems such as resisting medium seepage, and need regular inspection, often just needed in several years to change fully.Frequent maintenance is changed and has been had a strong impact on its applying in actual engineering.
Summary of the invention
In order to improve the job stability of existing suspension TMD damping control device, prevent balancing weight at work shake and reverse, and overcome its damping unit and need shortcomings such as frequent maintenance replacing, the invention provides a kind of damping controller for suspended tuning mass damper, this device not only can reduce the horizontal vibration with a plurality of directions of control structure, and avoided reversing and shaking of balancing weight, and new damping mode can use for a long time and need not maintain and replace.
The technical solution adopted in the present invention mainly comprises the universal hinge 8 of cross, balancing weight 3, rigid hanger 16, frictional damping sheet 20, extension spring 5 specifically referring to Fig. 2～7; Wherein, the universal hinge 8 of cross is connected with agent structure 1, frictional damping sheet 20 is set around the axle head of universal hinge 8 rotating shafts of cross, and balancing weight 3 hangs on the bottom of the universal hinge 8 of cross by rigid hanger 16, and the bottom of rigid hanger 16 adopts extension spring 5 to be connected with agent structure 1.
Two rotating shafts in the universal hinge 8 of described cross on the relative direction are fixed on the levelling plate 6 on the agent structure by top chock 7, connect step 14 in two rotating shafts on universal hinge 8 another relative directions of cross, step 14 is fixedly connected by being connected crossbeam with the upper end of rigid hanger 16, referring to Fig. 2, Fig. 3.
The deep groove ball bearing 11 of band dust cap all is set on described top chock 7, the step 14, is fixed in the axis hole of bearing support, referring to Fig. 4 by circlip for hole 13, baffle ring 10, shading ring 12.
Described frictional damping sheet 20 is positioned on the metal (upper seat by damping fin setscrew nut 21, and the termination of two frictional damping sheets is bound up by resistance trimming screw 22 and stage clip 23, referring to Fig. 7.
Extension spring connector 17 is installed in described rigid hanger 16 bottoms, the two ends of extension spring 5 all are connected on extension spring connector 17, the agent structure 1 by lifting bolt 19, the 17 upper and lower side settings of extension spring connector are by regulating its turn fine setting setscrew nut 18 of height up and down, referring to Fig. 5.
The present invention replaces flexible messenger wire 2 with rigid hanger 16, shake to avoid reversing with vertical of balancing weight 3, and the universal hinge 8 of cross that adopts can guarantee that TMD all plays the vibration damping control action to each horizontal direction.Abandon traditional piston type damper 4, and adopted the frictional damping sheet 20 that is wrapped in the universal hinge rotating shaft of cross position that the damping of TMD is provided, can regulate the damping of TMD by the pretightning force of regulating the frictional damping sheet easily.The frictional damping sheet is made simple, does not have problems such as the seepage of piston type damper and parameter instability, can use for a long time and need not maintenance.
After adopting said structure, can stabilizing effectively carry out vibration damping and vibration isolation, can carry out the adjustment of three controlling parameter easily as required, and can use for a long time and need not maintenance.
