This paper takes the small fish of Carangiform as the mimetic object. Through the bionics study to the principle of Carangiform"s propulsion, the robofish"s main body mechanism that has two degrees of freedom tail fin and single degree of freedom pectoral fin has designed. At the same time, the parameterized mathematical model of double-hinged propulsion system has established. The kinematics analysis, dynamics analysis to the propulsion process and preliminary hydrodynamics analysis to the tail fin and the pectoral fin have been completed. The dynamic equations to the propulsion system have been established.
本文以鲹科模式鱼类为仿生对象，通过对鲹科模式鱼类游动机理的仿生学研究，设计了两自由度的尾鳍推进机构及单自由度的胸鳍机构的机器鱼机械本体结构，建立了参数化的两关节尾鳍推进模式的数学模型，并对推进过程进行了运动学、动力学分析，建立了推进系统动力学方程，对尾鳍和胸鳍推进的水动力进行了初步分析。
