This dissertation sets up the kinematics model on the basis of the biomimetic study of lunate - tail propulsion steady swimming fish and of the analysis of fish body motion and caudal fin motion
本文在綜合國內外魚類游動文獻中的有關研究成果的基礎上，分析了魚類游動過程中魚體和尾鰭運動，建立了月牙尾推進模式穩態游動的運動學模型。The test proves that the caudal fin oscillation frequency, the maximum amplitude of vibration of caudal fin, the caudal fin strikes the water angle influence the fish ’ s speed ; the curve experiment has obtained curve radius of inertia advance curve and static curve ; the ups and downs experiment proves that the pectoral fin on different angle influences the fish to move ups and downs
加減速試驗論證了尾鰭擺動頻率、尾鰭后緣最大擺幅以及尾鰭的最大擊水角度對魚體速度的影響;轉彎試驗測得了機器魚慣性前進轉彎和靜止轉彎時的轉彎半徑;在機器魚的升潛試驗中論證了胸鰭不同轉角對升潛運動的影響。On the basis of image segmentation, this thesis mainly discusses the algorithm of automatic target tracking in sequence images on the sea. firstly, in terms of the characteristics of image on the sea, such as weak contrast between target and background, borderline between sky and sea, spoondrift and so on, a method called barycenter tracking which is based on intra - frame information from the sequence images is proposed, in which the threshold method is the key algorithm
在圖象分割演算法研究的基礎上，本文重點從兩方面討論了海上序列圖象中運動目標的自動跟蹤演算法:首先，針對海上圖象的特點，即背景與目標間的弱對比度、存在海天線、魚鱗光和目標拖尾等，設計了以閾值分割為核心的基於幀內信息的形心跟蹤方法。Some differences in value may be due to the omission of the fluid viscosity. the hydrodynamic interactions between two approaching or disparting spheroids, between two parallel torpedo - type or airplane - type platforms, between fore - and - afterward symmetrical uuv or platform and parent submarine have been investigated numerically, from which some interaction laws are drew
另外還進行了以下受力計算：兩個相互靠近或遠離的橢球體、魚雷型平臺在壁面或潛艇附近運動、飛機型平臺在壁面或潛艇附近運動、首尾對稱魚雷狀uuv與潛艇相對運動。This paper presents an overview of the swimming mechanisms and the caudal fin locomotion employed by fish. a practical method is brought forward that use the track of the caudal fin oscillating to study the locomotion of the robotic fish. and this paper mimic the bcf ( body and / or caudal fin ) propulsive fish with a three - link robotic fish model ( oucefish - i ) for oscillating foil propulsion, and then describes the design ( hardware and software ) of it in detail
本文對魚類的游動機理和尾鰭運動學原理進行分析，提出利用尾鰭擺動軌跡研究機器魚的運動學原理方法，設計並實現了一種三關節仿bcf （ bodyand orcaudalfin身體加尾鰭）高效推進方式機器魚模型（ oucefish - ） ，通過對機器魚的姿態、運行軌跡進行控制和分析，並對機器魚的實驗結果做了分析，達到研究分析機器魚的運動學原理的目的。The second section describes the morphological features and the swimming mechanisms of fish and explains the reason why this paper chooses bcf propulsive fishes as the model
在第二部分里描述了魚類游動機理和行為特徵，並對本文為何選擇bcf推進式魚類作為仿生對象作了解釋，並說明了尾鰭運動學參數和受力情況。分享友人
