摘　　要：本文基于线性切片理论,结合船舶在波浪中运动时历的数值模拟方法,考虑船舶表面点的运动与波浪的相位关系,给出了船舶表面点的入水速度的预报方法,再运用二维剖面入水砰击压力与入水速度之间的关系,对船舶表面入水点的砰击压力进行了预报。最后,给出了一条船的计算实例。Based on the ship linear strip theory,the time domain method is used to present the forecast method of ship sections inserting velocities under considering the relationship of the phase between waves and ship motions.Then two dimension section slamming empirical formula is used to calculate the slamming pressures of ship surface point.Finally,the examples of a ship are shown.
