船舶操纵运动数学模型研究

A Study on Ship Maneuver Mathematic Model

本文共分3个部份:第一部份阐述了船舶操纵运动数学模型的建立,选择了解析式水动力模型结构;第二部分依据实船试验结果,对船舶运动数学模型进行相似性率定,通过数值模拟和相似性分析,数学模型取得了与实船试验非常接近的结果;第三部分对建立的数学模型作了综合评价,认为达到了工程实用要求。

This paper includes three parts: the first part explains how to set up a ship maneuvering mathematic model with a structure of analytic hydrodynamic model; the second part discusses the similarity verification to ship maneuvering model on the basis of the result from the test on board. Both numerical analog and similarity analysis showed that mathematic model is very close to the test result; the third part is a comprehensive evaluation of the mathematic model which indicates that the model has reached the requirements of engineering practice.
