基于仿生学的舰船外型设计研究

Research on ship exterior design based on bionics

本文基于仿生学,着重对海豚尾部摆动运动学和动力学进行分析,给出鱼体波幅曲线,对海豚运动曲线进行分析,同时研究海豚的瞬态速度变化曲线;研究船舶的型线设计方法,着重分析融合技术、叠加扰动面技术以及横剖面移动技术3种设计方法,并探究基于NURBS曲线的船舶型线设计方法;最后对船舶外型优化进行仿真设计,给出船型优化前后的仿真结果。本文研究有助于我国船舶外型设计技术的发展。

This article studies bionics,with a focus on analyzing the kinematics and dynamics of dolphin tail swinging.The wave amplitude curve of the fish body is presented,and the motion curve of the dolphin is analyzed.At the same time,the transient velocity change curve of the dolphin is studied;Studied the design methods of ship profiles,with a focus on ana-lyzing three design methods:fusion technology,superimposed disturbance surface technology,and cross-sectional move-ment technology,and explored the ship profile design method based on NURBS curves;Finally,simulation design was carried out for the optimization of ship shape,and the simulation results before and after ship shape optimization were provided.This study contributes to the rapid development of ship exterior design technology in China.
