Yurales (Oiles’ Residential Vibration Damper)

Vibration dampers, which have been used in numerous high-rise buildings, have been developed for residential use.

Vibration dampers are effective at damping a wide range of vibrations from small tremors to major earthquakes.
A simple structure and low cost.
Friction materials that do not cause friction noise or vibrations (stick-slip) are used.
Fatigue life is not a concern, so the product is able to withstand repeated actuation and does not need to be replaced.

Operating principle

The pressurized pipe is secured with bolts to apply axial force to the friction material. Relative movement of the pressurized pipe and rod generates frictional force on the friction surface, producing damping force.

Basic characteristics

Oiles residential vibration dampers have a high initial stiffness and hysteresis characteristics close to perfect rigid plasticity.
However, action is slightly dependent on speed at low speeds, so the hysteresis angles are rounded .
