摘　　要：针对液货船舱晃荡载荷预报问题,进行了单自由度简谐运动激励下液舱模型试验,研究冲击压力特性,并选择70%H装载水平工况开展数值计算比较,结合试验结果得到计算预报的修正系数,同时用简单解耦方法根据单自由度修正系数对纵横摇耦合运动下的压力计算结果进行修正,所得结果可为晃荡载荷工程评估提供参考。The main aim of this paper is to estimate of sloshing loads in the tank of liquid cargo carriers. Sloshing model test with a 1/38 scale tank was carried out for simple harmonic motions to investigate vari-ous characteristics of impact pressures; and, numerical simulations were performed and validated for the same cases in 70%H filling depth. Sloshing pressures along the tank wall in coupled motions were also calculat-ed and revised against experimental data based on similarity transformation, which can provide references for evaluation of sloshing loads.
