摘　　要：针对五体船型的特点,基于STF切片理论,计入船体运动时湿表面的变化及其对船体流体动力性能的影响,提出了五体船纵向运动预报的一种工程算法.计算结果和五体船模试验结果在多个工况下进行了对比.结果表明,该算法对五体船运动预报具有相当的准确性,且简单实用,对五体船的主尺度、侧体位置优化等方面有着积极的意义.According to the characteristics of pentamaran, an engineering method for predicting the longitudinal motion in waves was presented based on the STF strip theory with the extension of taking into ac count the instantaneous variation of the wetted hull surface during motions and its effects on the ship hy drodynamic characteristics. Calculation and ship model experimental results were compared in several ship speed and wave cases, which proves that this method is reasonably precise for the prediction. This method can be widely applied in the principal dimensions and sponsons＇ positional optimization due to its simplicity and efficiency.
