Calculation of Added Mass and Added Moment of Inertia for Chine Hull by Strip Method

단일배골형선(單一背骨型船)의 부가질량(附加質量) 및 부가관성(附加慣性)모우멘트의 일계산(一計算)

The added mass and the added moment of inertia of a hard chine hull for heave and pitch were calculated by strip method. For the $k_2$ coefficients, Hwang's values for the straight-framed sections were used and for $k_2$ coefficients Porter's values for ellipses were used in the calculation. Comparisons on added mass and added moment of inertia of hard chine hull with those of ordinary hull form were briefly discussed. The results of the calculation for hard Chine hull give greater valves than ordinary ships at zero Froude Number. Beam draft ratio seems to be much influenced on the added mass and added moment of inertia.
