Abstract EN
The vibration transmission performance of a floating raft system with attached pipes is investigated in this paper.
The frequency response function-based (FRF-based) substructure synthesizing method whose accuracy has been verified by numerical simulations and experiment is applied for modeling the system.
The power flow through the transmission paths is used for exploring the additional vibration transmission path provided by the attached pipes.
The results show that the existence of the additional transmission paths caused by the pipes breaks the symmetries of the system, which leads to the enhancement of the coupling between each substructure.
Consequently, it degrades the vibration isolation performance of the raft system.
Moreover, a parametric study is performed to investigate the effects on the mean-square velocity of the hull of the attached pipes, which gives a brief guideline for designing the attached pipes.
