摘　　要：将白噪声技术引入到数值造波领域,采用计算流体动力学(Computational Fluid Dynamics,CFD)方法实现了基于白噪声波谱的舰船摇荡响应幅值算子的求取,计算结果与荷兰代尔夫特理工大学(Delft University Technology,DUT)相同傅汝德数下规则波船模水池试验结果进行比对,效果良好,有效地克服了传统上计算舰船摇荡响应幅值算子方法中效率低和精度差等不足,拓宽了舰船摇荡响应幅值算子的求取途径。This paper takes the white noise technology into the numerical wave generation field. The computational fluid dynamics method is used to realize calculation of RAO based on white noise spectrum. Compared with the ship model pool experiment in the same Froude number made by Delft University Technology（ DUT）,the calculation result is good. This method effectively overcomes the shortage in traditional way of calculating the RAO of ship＇s rocking,such as inefficiency and low calculation accuracy. The method also broadens the research areas of calculating the ship＇s RAO.
