摘　　要：基于切片理论计算在诸规则波中的舰船多自由度运动响应 ,并以此为样本训练模糊神经网络 ,最终建立起一种新的舰船在随机波浪中的多自由度运动模型 ,并通过算例验证该方法的实用性和可靠性。Based on the slice theory,the motional response of vessel with multi degrees of freedom in a series of regular wave is calculated,which is applied as a sample for training the fuzzy neural network.Finally,a new motion model of vessel with multi degrees of freedom in random wave is put forward and is examined by calculating an example to tesify its applicability and reliability.
