The vibration transmission characteristics of a three-degree of freedom nonlinear floating raft isolation system arestudied in order to analyze the influence of magneto-rheological damper on primary resonance attenuation. A revisedBingham model verified by experiment is adopted to describe the nonlinear magneto-rheological damping force, and thedissipated energy based on the model is given which is more than general viscous damper.Then, the approximatelyanalytic solution for primary resonance of floating raft isolation system is obtained by means of averaging method, and itis compared with numerical integration solution. Force transmissibility is proposed to evaluate the effectiveness ofmagneto-rheological damper.
