- 中文摘要: 將福祿-基若夫對船體所在處壓力分佈修正因戶併入撞擊模式後,可據以探討高速滑航快艇在規則波浪中之運動性能。 計算所得運動參數,如起伏、縱搖情形與其相位差、以及重心與船艏處重力加速度與費士瑪所得實驗數據相較,結果吻合。 改良喬森方法,利用計算所得起伏、縱搖等運動參數,可據以探討快艇在波浪中運動時阻力增加情形。圖6顯示費士瑪所得實驗數據適位於二組增加阻力計算值之間,一組考慮撞擊時水位興起效應,另一組則未考慮該效應。
- 英文摘要: An impact model incorporating dynamic corrections to the Froude-Kriloff hypothesis is formulatedto study high-speed planing boat motions. Computed motion parameters, such as heave, pitch, heaving and pitching, phase angles, and accelera-tions at CG and bow positions, compared with experimental results reported by Fridsma nicely. Added resistance resulting from boat motion in waves could also be computed by modified Joosen'smethod. Computed results compare nicely with experimental data reported by Fridsma.
