摘　　要：将一种现有的工程算法引入五体船纵向运动预报,该方法基于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。计算结果和试验数据在多个航速和波浪工况下符合良好。采用这种方法实现了前侧体的位置优化。The method is based on the STF strip theory with the extension of taking into account the instantaneous variation of the wetted hull surface during motions and its effects on the ship hydrodynamic characteristics. The predicted results and ship model experiment data are in good agreement in several ship speeds and wave cases. With this method, the fore sponsons＇ positional optimization is carried out.
