船型参数的流体动力设计

A Hydrodynamic Design of Ship Hull Parameters

本文提出一种综合考虑流体动力性能的船型平衡设计方法(BDM),即首先根据本文提出的综合指数R选择流体动力性能优良的母型船,然后利用正交设计方法优化母型船,以便得到满足设计要求的船型。同时给出了一个利用文中提供的设计方法完成的渔船优化设计实例。

A balanced design method that takes various hydrodynamic perfor- mances of ship hulls (BDM) into consideration is presented in this paper. This method can be stated briefly as follows: First, a parent ship with good hydro- dynamic performances is selected by the synthetic indexes used in this paper. Then the parent ship is optimized by orthorgonol design in order to obtain a ship form which satisfies the designer's requirements. By using the design procedure presented in this paper, an example of optimization design of a fishing boat is given.
