【摘要】 针对实际鱼类胸鳍运动的随机性、不确定性和复杂性等问题给胸鳍推进机理和推进性能研究带来的挑战与困难,以及柔性胸鳍仿生研究所存在的问题,在对太阳鱼胸鳍的结构和运动特征进行大量观测研究的基础上,分阶段建立柔性胸鳍推进运动的运动学模型,并对其运动形态的变化过程进行仿真分析。仿真结果表明,所建立的运动学模型能够较好地描述胸鳍推进运动的运动规律和运动形态。此研究可为柔性胸鳍推进机理、推进性能和仿生等方面的深入研究提供理论依据。更多还原

【Abstract】 Aiming at the difficulties in the research on the propulsion mechanism and propulsion performance caused by the randomness,uncertainty and complexity of real pectoral motion,and the problem in bionic research on fexible pectoral fin,a kinematics model of propulsion motion of flexible pectoral fin is established in stages based on the research on a great deal of observation of the structure and motion characteristic of sun fish pectoral fin,then the simulation analysis of the change process of its morphology is developed.The simulation result shows that the kinematics model established describes the motion law and morphology well.Therefore,the research settles the theoretical basis of the further research on the propulsion mechanism,propulsion performance and bionics of flexible pectoral fin.更多还原
