When, resisting medium 3 is substantially reduced by shear rate.Do not only reach the purpose of optimization design, the energy dissipation behavior of viscous damper,
Also improved a lot in durability and stability.
2nd, because the wall thickness of piston sheet 4 is relatively thin, when damper is exerted oneself less than ultimate load, piston structure is stable, piston with
Cylinder gap is definite value, and damper energy dissipation behavior is stable, and hysteresis loop is full；It is living when damper is exerted oneself more than ultimate load
Elastic deformation occurs for elastic deformation set 4-2 on patch 4, and damper enters unloaded state, and protection damper structure is without damage.Cause
This can be avoided hysteresis loop not full completely, the problem of power consumption rate is low, while also effectively improving viscous damper in accidental loads
Under self-protection function.
For having that the viscous damper for the combined type multistage energy-dissipating type adaptive damping for verifying the utility model design is brought
Beneficial effect, the applicant has carried out the contrast of relevant parameter for the combined live patch 4 of existing one-piece piston and the design
Experiment.
Fig. 6 is the hysteresis loop figure of existing one-piece piston, the combined live patch 4 that Fig. 7 designs for the utility model
Hysteresis loop figure.By contrast, Fig. 6 hysteresis loops are closer to ellipse, and hysteresis area is relatively small, power consumption rate compared with
It is low；Fig. 7 hysteresis loops are full, and power consumption rate is higher.
Fig. 8 is the energy consuming curve figure of existing one-piece piston；Fig. 9 is the combined live patch 4 of the utility model design
Energy consuming curve figure；The load circulation of the identical quantity of the circle of loading 30, it is possible to find, the load of combined live patch 4 is steady, and attenuation ratio can control
5% or so, without substantially decay；Substantially, attenuation ratio is more than 20%, and decay is obvious for one-piece piston load alleviation.
Therefore under identical operating condition of test and objective condition, combined live patch 4 is regardless of the load under cyclic loading
Attenuation rate, or on seismic wave energy consumption effect, better than one-piece piston structure.
Although the foregoing describing embodiment of the present utility model, those skilled in the art should manage
Solution, these are merely illustrative of, and can make various changes or modifications to present embodiment, without departing from original of the present utility model
Reason and essence, protection domain of the present utility model are only limited by the claims that follow.
