Abstract
The utility model belongs to the technical field of structural shock-absorbing control, and relates to a compound low yield point metal-viscoplastic damper, wherein viscoelastic material 2 is filled between upper and lower cover boards 3 and a sliding steel plate 5 as well as between a middle steel plate 4 and the sliding steel plate 5; the viscoelastic material 2 is connected with the upper and the lower cover boards 3, the middle steel plate 4 and the sliding steel plate 5 in a vulcanization manner; low yield point metal 1 are embedded in grooves that are formed in the symmetrical positions on the upper and the lower surfaces of the middle steel plate 4, and are bonded with the viscoelastic material 2 in a vulcanization manner; in addition, a bolt 6 penetrates through the upper and the lower cover boards 3 and the middle steel plate 4, and can fix the upper and the lower cover boards 3 and the middle steel plate 4 and compress the low yield point metal 1, the viscoelastic material 2 and the sliding steel plate 5 through a lock nut 7. The compound low yield point metal-viscoplastic damper utilizes the low yield point metal and the viscoelastic material to consume energy at the same time, so that the energy consumption and shock-absorbing capability of the damper is improved, the energy consumption effect of the metal damper under small and middle vibration is improved, the occupied area of the damper is decreased, the laying position is flexible, the material can be obtained economically, and the practicability is stronger.
Description
Technical field
The utility model belongs to structural damping control technique field, relates to a kind of low-yield metal-viscoelastic composite buffer.
Background technique
Structural vibration control can improve the shock resistance of structure effectively and combat a natural disaster performance, is the active and effective countermeasure of antidetonation mitigation.As a kind of effective controlling method, energy-dissipating and shock-absorbing is by increasing structural damping, and absorption and consumption earthquake are input to the safety of the energy of structure with the protection agent structure.Metal damper is a kind of damping device that utilizes the shearing plastic deformation dissipation intake of low-yield metal, and hysteresis is full, and power consumption is stable, and is functional, has a good application prospect and higher promotional value.The existing general initial stiffness of metal damper is all bigger, and damper does not enter the surrender power consumption as yet fully under the medium and small shake effect, and the energy-dissipating and shock-absorbing effect is also not obvious, and the energy-dissipating and shock-absorbing advantage of damper is more remarkable under big shake effect.The initial stiffness that reduces the low-yield metal damper is significant for the application of such damper.
The model utility content
The utility model purpose is at the bigger problem of the initial stiffness of metal damper, and a kind of low-yield metal-viscoelastic composite buffer is provided, and improves the energy-dissipating and shock-absorbing effect under the little middle shake effect of metal damper.
The technical solution of the utility model is as follows:
Low-yield metal-viscoelastic composite buffer, include low-yield metal 1, viscoelastic material 2 and cover plate 3 up and down, middle steel plate 4 and sliding steel plate 5, wherein: fill viscoelastic material 2 up and down between cover plate 3 and the sliding steel plate 5 and between middle steel plate 4 and the sliding steel plate 5, viscoelastic material 2 and cover plate 3 up and down, middle steel plate 4, sliding steel plate 5 sulfurations connect, low-yield slug 1 is embedded in the groove that 4 liang of surface of contact symmetrical positions of middle steel plate offer, and with viscoelastic material 2 sulfuration bonding, bolt 6 passes cover plate 3 and middle steel plate 4 up and down, by locking nut 7 securing cover plates 3, middle steel plate 4 also compresses low-yield metal 1, viscoelastic material 2, middle steel plate 4 and sliding steel plate 5.
Effect of the present utility model and benefit are to combine under the stable and any vibration condition of viscoelastic damper of metal damper hysteresis all advantages of power consumption, form two kinds of compound power consumptions of mechanism, solved the excessive problem of metal damper initial stiffness, reduced taking up room of damper when improving the energy-dissipating property of damper, the application and the popularization of metal damper has been significant.
