Length it is longer, be not suitable in space installation in small distance；2nd, it is difficult and even impossible two springs of guarantee in technique
Rigidity (including tensible rigidity and compression stiffness) is equal, therefore wind direction difference damping effect is difference；3rd, damper can not be changed
Initial stiffness, reach default wind resistance rank, reduce the purpose of damping cost；4th, a helical spring is at the same time in stretching and compression
Work under two states, the metal material and production technology of existing spring are difficult to meet the requirements, can only be by reducing helical spring
Regime of elastic deformation come realize stretching with compression two kinds of working statuses, this obviously can cause the wasting of resources.To by compound bullet
Spring, which is used for wind-resistant vibration, obviously also to be needed to form wind resistance damper using two complex springs as above-mentioned utility model patent, and
The damper being composed so obviously also possess above-mentioned patent it is the same the shortcomings that.
In addition, design of the people for the anti-seismic structure of anti-seismic structure especially high-rise pursue a kind of " anti-" and
The anti-seismic performance for the synthesis that " consumption " is combined, i.e., anti-seismic structure can be that building main body carries under the action of weak wind shake and small earthquake
The effect of external load is resisted for extra additional stiffness, the integrality of retainer body structure, avoids in main structure body appearance
Portion is damaged；Shake in high wind and then start yield deformation with anti-seismic structure under the action of violent earthquake, pass through the damper in anti-seismic structure
Damping action come the external energy that dissipates, main structure body is shaken in high wind and is unlikely to be seriously damaged in violent earthquake or even falls
Collapse.This just requires that rigidity can be kept under the action of exterior weak load applied to anti-seismic structure, does not deform；In exterior intense loading
Energy consumption can be then deformed under the action of lotus.But existing isolated component, either metal spring damper or rubber air bullet
