Primary Research on Synthetical Optimization of Rapidity and Maneuverability of High-speed Monohull Ship

以MATLAB 6.5为工作平台,使用仿真软件Simulink对高速单体船快速性以及结构特性的联合系统建立了数学模型。通过程序计算比较得出各设计变量的较优组合。在此基础上,从混沌变量、权系数不同、目标函数形式以及敏感变量等多个方面对结果的影响做出了分析。计算结果表明:变尺度混沌算法是有效且可行的。

Based on the software MATLAB, the mathematic model of the combined system with rapidity and structural characters of a high-speed monohull ship is established by using the simulation module Simulink. Through the computation and comparison, the optimal combination with different design variable is obtained. On the foundation, the different aspects, which can affect the result, such as the chaos variable, the weighting coefficients, the goal function as well as the sensitive variable are analyzed. Results from calculation show that the mutative scale chaos algorithm is effective and feasible.
