The authors have developed fluid inertia damper using MR fluid in order to obtain a variable inertia effect. From the experiments, it seemed to be that the inertia effect was slightly switched, but very small. In this paper, to get much inertia effect, the damper was improved by using long bypass pipe of stainless steel, and 24 electromagnets were installed along the long by-pass pipe. Dynamic property was investigated experimentally and theoretically.
