机器鱼的运动仿真方法

采用轴变形方法模拟机器鱼的运动。根据用面元法计算的机器鱼水动力结果和垂直面内胸鳍的攻角与升力的关系,建立了机器鱼的运动模型,并采用轴变形方法模拟了机器鱼在水平面内的直航运动。根据仿真试验结果的误差可以认为,该方法实现的运动仿真与真实的鱼的运动基本一致,这对以后的工作有较大的指导意义。

Movement Simulation Method of Robot Fish

The axial deformation method was used to simulate the motion of robot fish in this paper. Based on the hydrodynamic results which are calculated by the panel method, and the relations between pectoral fins attack angle and lift, the motion equation in vertical plane is done, and the axial deformation method has been used to simulate the robot fish moving ahead in horizontal plane. From the errors of the result, the simulating movement is consistent with the tuna fishs motion, and this is practicable to the future research on robot fish.
