| Abstract: | A method about modeling the 1/3 octave spectral of naval ship radiated noise was introduced.Based on the study of the characteristic rule of the machinery noise,propeller noise and propeller-shafting-submarine body system' vibration noise,the model of machinery and propeller's rated sound spectrograph were established,while the response function model of propeller-shafting acting of submarine body was obtained.According to the relationship between the propeller noise and the speed of submarine,the 1/3 octav... |
