The sixth section gives the experimental results in the quasi - steady flow around the caudal fin and mimic the forward swimming using the caudal fin as the propulsor. and then review the speed and track of the robotic fish swimming when locomotion parameters are set in the experiment condition
第六部分通過機器魚的自主游動實驗，初步模擬了機器魚利用尾鰭擺動推進前進，考察了實驗條件下設定魚的尾鰭擺動相關參數的情況下魚的游動速度和尾鰭的擺動軌跡情況。 -
It can move forward, backward or brake depending on the undulatory motion of the flexible fin
它依靠柔性長鰭的波動運動來實現載體的前進、後退、制動等各種機動動作。 -
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。 -
Based on the strategy, this paper gives the equation of caudal oscillating track when the robotic fish swimming forward with a certain speed by using two - link caudal fin
根據以上模型，本文給出了機器魚在某個時間段勻速下機器魚兩關節尾鰭擺動軌跡方程。 -
Abstract : the review presents the recent status and achievements on numerical simulation studies of solid rocket motor chamber internal flow field from three aspects, including numerical analysis of internal flow during the ignition transient period, fin - slot flows in solid rocket motor, and calculation of particle trajectories and slag deposition. it also puts forward the focal points of research on numerical simulation of solid rocket motor chamber internal flow field in our country
