摘要：
The analysis of underwater structure vibration and noise control has been paid more attention now. The problem about propeller exciting force transfers from shafting, the bearing supporting to structure, causing structure radiated noise is less studied. If the problem is solved, the underwater structure noise will be decreased greatly. In this paper, the characteristic of shafting and underwater structure coupled system vibration power flow is analyzed. Because the analysis model is complex, the finite element method was adopted to calculate the system input power, transmission power at each bearing supporting. Furthermore, the effects of longitudinal, lateral exciting force and moment on transmission power characteristic are studied.
