Abstract
In this paper, MDOF roof isolation structure with the MR damper is analyzed. Firstly, based on the theories of big mass ratio TMD control, the dynamic characteristics of the roof isolation structure are studied. The main effects are gain and the logical system is set up. Secondly, isolation is controlled by MR damper to avoid the shortcoming that range of control is very narrow. The passive control and semi-active control are adopted to improve the effect. Finally, the 3-degree of freedom roof isolation structure with MR damper is simulated. The results show that the scheme of roof isolation with MR damper is efficiency for reducing vibration of the MDOF structure.
