Research on the joint vibration reduction of dynamic absorber system and floating raft vibration isolation system

摘要

In floating raft vibration isolation system, two or multi-machines are generally mounted on raft frame simultaneously. If the auxiliary machines of which are designed as dynamic absorber through configuring their isolator parameters rationally, the joint vibration reduction of dynamic absorber system and floating raft vibration isolation system could be realized. The power flow transmitted from excitation machine to flexible rectangular plate foundation is presented in themethod of mobility power flow and the harmonic effect of the auxiliary machines is investigated in this study.
