  • The hull system is an important path for radiating propeller noise. Propeller excitation must be transmitted by the thrust to the hull system. As such,the study of the relations between force transmission and the vibration and sound power of submarines is very important. To this end,this paper aims at propeller excitation force,lateral excitation force and vertical excitation force. The transmission modes of the force loaded by the thrust system are analyzed,and the combined fluid-structure interaction,vibration and sound power of the finite element model of the submarine are analyzed. This provides a new method for analyzing the vibration and radiation of submarines under propeller excitation force.
