| Abstract: | Aimed at the installation of the machines on the flexible foundation, the dynamic transmitting characteristics of a complex floating raft system have been theoretically studied by the substructure mobility method. Further, the power flow transmissibility has been proposed and analyzed as a new comprehensive evaluation standard and its validity has been proved theoretically. |
