摘　　要：为确定船舶下行过弯控制航速,针对内河弯曲航道通航水流条件及船舶在通过弯曲航道时的操纵特点,提出船舶下行过弯航行控制策略,构建了基于允许正常偏航条件下的弯曲河段船舶下行控制航速的计算模型,并以5000 t级散货船为对象,计算得出了在不同水流条件下的下行过弯控制航速,计算结果与目前有关内河引航机构对船舶的航速控制符合度高。研究成果对提高弯曲航道通过能力、保障船舶过弯安全均具有积极作用,也可为船舶自主航行的航速控制提供参考。To determine ship downward cornering speed control,based on the navigation condition of curved channel and ship maneuvering characteristics,put forward the ship downward bending navigation control strategy and construct the ship control speed calculation model under normal yaw condition when passing curved channel.Then take the 5000-ton bulk carrier as the research object,the speed of the descending overturning control under different flow conditions is calculated,also the calculated results are in good agreement with the speed control of the relevant inland river pilot institutions.The research results have positive effects on improving the passage ability of curved channel and ensuring the safety of ship bending,and can also provide reference for the speed control of ship autonomous navigation.
