A large-amplitude oil damper system with twice the stroke and velocity of a normal oil damper has been developed. The damper system consists normal oil dampers connected in series. In order to make the displacement of dampers in the system same, “displacement adjustment mechanism” is connected in parallel. The mechanism consists of right-hand threads and left-hand threads with same pitch. We made a full-scale prototype of the system and conducted loading tests. As a result, it is confirmed that the displacements of each damper are same, and the stroke and velocity are twice that of a normal oil damper.
