Paper Abstract
Magneto-rheological fluid is the fluid which is controllable with applied magnetic fields. This fluid is effective as a semiactive control device such as MR damper. In this paper, a new MR technology is developed with squeeze mode smart damper. And various dynamic tests are performed to identify the dynamic characteristics of this device. This squeeze mode smart damper can be used permanently, and can be freely allocated at the sub-region of large structures such as buildings and civil engineering infrastructures. Various dynamic tests are carried out to evaluate the performance of the squeeze mode smart damper in many loading conditions. Force-displacement and force-velocity hysteresis loops are also investigated for evaluation of its dynamic performance. In order to predict the dynamic performance of this device, two types of analytical models are compared with experimental results. A power model based on the damping and velocity, and a Bingham model are adopted in the viewpoint of practical usage. These results verify that the developed smart damper is effective in semi-active control of civil structures.
