초록
This paper describes the time-domain numerical method for prediction of slamming loads on a ship in waves using the strip theory. Theslamming loads was calculated considering the relative vertical velocity between the instantaneous ship motion and wave elevation. Forapplying the slamming force on a ship section, the momentum slamming theory and the empirical formula-based bottom slamming forcewere used corresponding to the vertical location of wetted body surface. Using the developed method, the vertical bending moments,relative vertical velocities, and impact forces of S175 containership were compared in the time series for various section locations andwave conditions.
