摘　　要：在海洋平台附近,工作船的水动力性能会受结构物侧壁的影响而下降。基于Rankine源常值面元法,建立考虑岸壁和波浪作用的船舶水动力数值模型并在时域上求解。选取经典Wigley Ⅲ船模计算各波长下的水动力和运动响应幅值,并将模拟结果与其他方法的计算结果对比,验证了数值研究方法的合理性和可靠性。通过参数的敏感性分析,揭示航速、波浪特征和侧壁对船模运动响应的影响,为船舶在复杂海域中的水动力响应实时预报服务。The structural sidewall of an ocean platform will affect nearby working vessels and a reduction in their hydrodynamic performance will result.Based on the Rankine source constant element method,a numerical model of the ship's hydrodynamic performance is established by considering shore walland wave action,and solutions are given in the time domain.Aclassic Wigley Ⅲ ship model is selected for numerical simulation of motion response amplitudes at various wavelengths,and compared with other calculation results to verify the rationality and reliability of the present method.Sensitivity analysis of parameters such as speed,wave characteristics,and sidewalls are conducted to reveal their influences on the motion response of the ship model in waves,achieving real-time prediction of ship hydrodynamic response in complex sea areas.
