摘　　要：为精确获取最小推进功率评估所需的低航速恶劣海况波浪增阻值,应用时域匹配泰勒展开边界元方法(TEBEM)预报了3艘船舶在最小推进功率评估所对应的海况下运动响应和波浪增阻,并与模型实验结果进行了对比分析。结果表明,时域匹配TEBEM获得的船舶规则波运动响应和波浪增阻传递函数与模型实验吻合较好,数值预报方法获得的不规则波波浪增阻值与模型实验对应的结果误差在15%以内,具有较高的数值精度、计算效率及工程应用价值。论文研究成果为中国向MEPC会议提交最小推进功率提案提供了技术支撑。In order to accurately obtain the value of wave added resistance at low speed and adverse condition required for the minimum propulsion power assessment, a numerical prediction method based on time domain hybrid Taylor Expansion Boundary Element Method(TEBEM) is applied to three ships for numerical prediction of motion response and added resistance in waves under the sea condition corresponding to the minimum propulsion power assessment, and the numerical results are compared with the results derived from seakeeping model tests. The comparison shows that the numerical results of ship motions and added resistance in waves obtained by time domain hybrid TEBEM are in good agreement with experimental results, and the error between the value of irregular wave added resistance obtained by numerical prediction method and model test is within15%, which shows the high numerical accuracy, calculation efficiency and engineering application value. The research results provide technical support for China to submit the proposal of minimum propulsion power to MEPC.
