Classification 
HDR high damping isolation rubber bearing according to the functional form is divided into fixed isolation bearing and sliding isolation bearings.
Fixed displacement of rubber bearing realized by shear deformation, the level shearing of the rubber can bear large horizontal force,
According to the connection structure is divided into Itype, IItype, Through the large displacement shearing deformation in  horizontal direction of high  damping rubber and hysteretic energy dissipation to realize isolation function.
 

Description
High damping rubber bearing is to join all kinds of chelating agent into natural rubber,can improve the damping properties of rubber,the bearings which is made of the rubber  with damping property is called the high damping rubber isolation bearings (HDR bearings).  High damping rubber  isolation,due to the high damping rubber,With the functions of  stable support, damping and elastic reset ,it can absorb seismic energy in the quake, reduce the earthquake effect, and can be used as isolation device alone.
 

Features
The vertical bearing capacity, level of restoring force and damping be trinity
2. Bearing hysteresis characteristics (load - deformation curve) satiation, energy consumption significantly;
3. Rubber formula improvement,The equivalent damping ratio can reach more than 12%;
4. Maintenance cost is low(Don't  need other damping device);
5. Small residual deformation after the earthquake,don't need to change;
6. The surface of high damping bearing [1] covered with rubber cover,Protect the internal rubber is not affected by ozone, ultraviolet radiation,has good aging resistance,50 years of equivalent damping ratio lower less than 2%;
7. Low  temperature dependency of HDR high damping rubber,widely used in different climate regions;
8. HDR high damping rubber is the same as natural rubber with superior creep properties;
9. Environmental and contamination.
