High damping rubber bearings
High damping rubber bearing, which is made of high resistance rubber bearing in accordance with the national standard GB20688 design are also called HDR support, it is added in natural rubber compounding agent, used to improve the damping properties of rubber (increasing hysteresis loss and reduce the storage modulus), laminated products and then use this with a damping effect of rubber the approximate and common rubber bearing structure of a steel plate and a rubber composition by thermal curing.
The product has good isolation performance and wide range of application. It is a new type of bridge and building construction products with higher cost performance. Because of its simple manufacturing technology and reliable mechanical properties, it has been widely applied and developed after the 5.12 China earthquake.
Product features:
1. Vertical bearing capacity, horizontal restoring force and damping (energy absorption) trinity;
2. The hysteretic characteristic of support (load deformation curve) is full and the energy consumption is remarkable;
3. Rubber formula improved, the equivalent damping ratio of more than 12%;
4. Low Maintenance management cost (without other damping device);
5. After earthquakes, the residual deformation is very small and needs no replacement;
6.High damping bearing surface covered with rubber protective layer, protect the internal rubber from ozone, ultraviolet light influence, have better aging resistance, 50 years equivalent damping ratio is less than 2%;
7.HDR high damping rubber has low temperature dependence and is widely used in different climatic regions;
8.HDR high damping rubber, like natural rubber, has superior creep properties;

Design principle:
Vertical bearing capacity: through the steel plate to provide stable and reliable vertical bearing capacity to ensure the daily use of buildings safe and reliable.
The level of stress, with high strength using natural rubber, and the steel plate bonding reliability, the horizontal direction in daily vibration, wind load and earthquake giant shock wave impact, will not guarantee the building because of the sudden internal damage caused by failure.
Isolation design theory: the damping formula performance special consumption transfer in the earthquake vibration energy level, when the earthquake strikes on buildings provide support vertical, horizontal direction will not transfer energy to all buildings in seismic wave action in reciprocating vibration energy is converted into heat consumed, greatly reduce the level of the earthquake force of the wave structure under bad effect. Thus reducing the earthquake damage to the building capacity.
