摘　　要：研究液货晃荡对油船运动响应及结构响应的影响。在考虑液货晃荡与忽略液货晃荡情况下,考察不同载液率与不同浪向角时油船的横摇运动响应。分析液货晃荡对油船的总纵强度响应的影响,包括最大扭矩、最大垂向弯矩、最大水平弯矩作为控制参数时的设计波参数及结构应力分布特征。分析液货晃荡对油船的疲劳强度响应的影响,包括满载状态下的疲劳损伤沿浪向角的分布及疲劳评估。这项研究对油船结构设计及评估具有一定的参考意义。Influence of liquid sloshing on motion response and structural response of an oil tanker is studied. Rolling motions, with and without thinking about liquid sloshing are compared trader different liquid load rate and wave direction. Influence of liquid sloshing on structure longitudinal strength is analyzed, including designed wave parameters and characteristics of the stress distribution, with the maximum torque, maximum vertical bending moment and maximum horizontal bending moment as the control parameter respectively. Influence of liquid sloshing on structural fatigue strength is analyzed, including fatigue damage and fatigue assessment. The research is of certain significance of reference for structural design and assessment of an oil tanker.
