A REAL SCALE PERFORMANCE TEST OF A HIGH CAPACITY OIL DAMPER

Abstract

The authors developed an oil damper with a new and novel configuration. That has the high damping capacity, 6000kN force in maximum. Through a real scale performance test with conditions of velocity of 450mm/s or of displacement amplitude of 184mm both in maximum, it was confirmed the developed damper possesses the designed characteristics. In another test using earthquake responded waves, the device showed an expected performance, as well.
It was also found out that a new test method, employing the feature on the configuration consisted of three element dampers, and will make product testing possible, was precise enough.
