| Abstract: | These predictions presentra practical method for estimating the wake factor and controlling the vibration response of ship-girder in the ship design step. The wake factor empirical formula is obtained from the measurements of wake survey on 15 single screw ship models. The formula of vibration responte of ship -girder inducted by propeller excitation is based on the measured vibrbtion response of 10 ships. They are all summarized by means of regression analysis me- thod, |
