Power flow analysis for a new isolation system—flexible floating raft
A new model for a raft isolation system is proposed, in which the raft supports two machines on a flexible foundation via a series of isolators. The interaction between the flexible floating raft and the non-rigid foundation is studied by the novel approach of power flow. The power flow input and transmitted in the complicated compound system are then formulated in closed forms, in which the coupling between the raft and the foundation is considered. The effect of the raft flexibility on power flow spectra is also revealed. This study shows that it may lead to an overoptimistic evaluation to the effectiveness of the raft isolation when simplifying the raft to an ideal rigid structure. Thereby, the reliable estimation and effective design for raft isolation system are provided

Abstract
A new model for a raft isolation system is proposed, in which the raft supports two machines on a flexible foundation via a series of isolators. The interaction between the flexible floating raft and the non-rigid foundation is studied by the novel approach of power flow. The power flow input and transmitted in the complicated compound system are then formulated in closed forms, in which the coupling between the raft and the foundation is considered. The effect of the raft flexibility on power flow spectra is also revealed. This study shows that it may lead to an overoptimistic evaluation to the effectiveness of the raft isolation when simplifying the raft to an ideal rigid structure. Thereby, the reliable estimation and effective design for raft isolation system are provided
