Space-saving damper provides significant resistance Advantages The damper offers stable performance even in extreme environments, because of its extremely low temperature dependency. It has superior durability and possesses damping capability to withstand the repeated impacts of earthquake. It can be used in many types of buildings with various features due to its wide ranging damping capacity. No maintenance is required as the viscous material remains stable over many years, and there is absolutely no leakage of fluid. There is no directional requirement for installation. Structure and Function Bingham damper, using viscous resistance of a special filler, consists of a fluid filled cylinder, a piston and a rod. Function of Bingham damper Bingham damper transforms the vibration from earthquake or strong winds into motion of a piston inside a cylinder filled with a special material to dissipate vibration energy. Basic Features This chart shows the relationship between resistance and displacement when the Bingham damper is subjected to the displacemnet expected during a major earthquake, verifying the stable performance of the device. Modelling of Bingham damper for structural analysis is straight forward as it is almost independent of vibration and temperature. * In the standard design, reaction force is from 15 to 300 tonf.

Test Performance Test Performance testing of the Bingham damper demonstrated that a stable damping function can be obtained with excellent damping capacity during vibration from major earthquakes and strong winds. Characteristic value within ± 5% of design value is obtained. Temperature characteristics Test The test results for the Bingham damper showed no significant changes of the resistance force at temperatures from -18 to 40 °C, demonstrating excellent characteristics as a damper. As an extra specification, performance in high temperature environments can be guaranteed up to 150 °C. Fire-resistance Test To verify the safety of the Bingham damper against fire, fire-resistance testing was carried out at 925 °C. As a result, no ignition or explosion was observed, demonstrating excellent fire resistance.
