【摘要】 针对浅水区域的滑落救生艇入水问题，建立了数值计算模型。针对救生艇入水瞬时的纵摇角速度影响，给定初始位置、速度和纵摇角条件，考虑三种顺时针纵摇角速度工况，研究了救生艇速度、位移和轨迹变化规律，获得了最大入水深度。结果表明，随着初始纵摇角速度增大，救生艇入水角度也随之增大，则有：1)艇首点的最大入水深度，三种工况值分别为自身艇长的61.14%、70.91%、82.61%；2)艇首点入水深度最大，艇首不触底。更多还原

【Abstract】 Considering water entry of lifeboat in shallow-water areas,the numerical models are established.Focusing on angular pitch velocity during lifeboat water entry,the research is conducted with given initial positions,velocities and pitch angles.And three numerical cases are determined considering three clockwise angular pitch velocities.The disciplines are studied on lifeboat velocities,displacements and trajectories.And the maximum depth values of lifeboat water entry are obtained The results show that the pitch angle of lifeboat water entry increases with the increasing of the angular pitch velocities,resulting in conclusions drawn:1) considering maximum depth values of water entry at the bow point cover 61.14%,70.91% and 82.61% of its length respectively;2) the depths of water entry reach the peak value at the bow point,and the bow grounding is avoided.更多还原
