The developed Rubber Damper Device consists of a tube cylinder with inner core which is moving inside the cylinder. The high damping visco-elastic material such as high damping rubber is mounted between the inner core and outer tube and bounded to both surfaces as energy dissipator members to absorb vibration loads.
During bridge or structural movement, the vibration is transferred to the inner core which is moving inside the outer cylinder. Therefore, the high damping rubber which located between the inner core and outer tube, dissipate the vibration effect by shear stiffness and damping action of rubber materials.
The experimental testing results for fabricated rubber damper device in lab scale which conducted using dynamic actuator at UPM, indicating 30% higher performance in comparison to viscous dampers and less manufacturing cost and also it is maintenance free (almost 30 years).
