摘　　要：考虑到澜沧江货船特有的大功率小吨位、浅吃水的船型配置特点,结合澜沧江500 t、300 t级机动船实船静水航速试验,分析试验结果与海军系数法、巴甫米尔法、爱尔法、兹万科夫法等现有航速估算方法计算结果的偏差,结果表明,提出基于相对航速、无因次功载比、阻力系数,以及综合因素4个层次的澜沧江货船静水航速估算思路与方法。Considering the unique configuration of large power,small tonnage,and shallow draft ship types of cargo ships in the Lancang river,combined with the still-water navigation velocity prototype tests of 500 t and 300 t class ships in the Lancang river,the deviation between test results and existing velocity estimation methods such as the Navy coefficient method,Pavmir method,Aier method andЭиванковmethod were analyzed.Based on relative velocity,dimensionless power-load ratio,resistance coefficient and comprehensive factors,the ideas and methods for estimating the ships’velocity in the Lancang river were developed.It was proved that the resistance coefficient method and the dimensionless power-load ratio method have higher accuracy;while the resistance method considers not only thrust characteristics of the propeller but also the resistance property.
