| 摘 要： | 可回转桨在船后形成复杂的流场，难以建立准确的数学模型，因此对其推力进行理论计算十分困难。本文根据实验数据，用神经网络辨识方法建立了船后可回转桨的水动力模型，并在此基础上研究了可回转桨的操纵性能。仿真结果表明：用神经网络系统辨识方法所建立的数学模型能够真实地反映可回转浆的推力特性。本文为研究复杂的水动力问题提供了一种行之有效的方法。

| Abstract: | There is a complicated fluid field following the ship movement because of the rotatable propeller. It is difficult to build an accurate mathematical model, and much to calculate the thrust of the rotatable propeller. In this paper we use the method of the neural network to build the hydrodynamic model of the rotatable propeller according to experimental data. On the basis of it, the maneuverability of the rotatable propeller is studied. The simulation results show that the mathematical model reflects the thrust characteristics of the rotatable propeller exactly. It is an effective method to solve the complicated hydrodynamic problems. |
