High Damping Rubber Bearing Hdr - China

High damping rubber bearing, also known as HDR bearing pad, is a kind of seismic isolation bearingsimilar with lead rubber bearing.

Made from special rubber with excellent damping attribute and layers of steel, the high damping rubber bearing has excellent flexibility, vibration reduction ability and high restoring ability.

Thus it is an important component of seismic isolation system and can effectively reduce the bridge and building structure damage caused by earthquake.

The high damping rubber bearing itself performs the isolation function and does not need to configure other devices, so the maintenance and management cost is low.

Working principle of high damping rubber bearing

By producing large deformation and small rigidity, the high damping rubber bearing has excellent seismic effect during the earthquake.

As the elastic stiffness of the bearing depends on its deformation degree.

When the deformation is small, the stiffness will be large.

The high damping rubber bearing has excellent seismic isolation function by this principle.

Characteristics of high damping rubber bearing

The hysteretic characteristic (load deformation curve) of high damping rubber bearing is full, which can play an isolation effect for wind vibration and large, medium and small earthquakes.

The high damping rubber bearing itself performs the isolation function and does not need to configure other devices, so the maintenance and management cost is low.

After a large earthquake, the high damping rubber bearing will not produce residual deformation, and the characteristic change is very small, so it does not need to be replaced.

The elastic properties and damping properties of high damping rubber bearings have little dependence on temperature, that is, they are less affected by temperature, so they are suitable for a wide range of fields.

The internal EPDM rubber is completely protected which is resistant to the ozone and ultraviolet, so it has better aging-resistant ability.

HDR high damping rubber has the same superior creep performance as natural rubber.

Applications

High damping rubber bearing is widely applied in the quake-prone areas for bridge, building and other construction structures.
