机器鱼游动性能改善方法

为了提高机器鱼的推进速度和推进动力,对机器鱼尾鳍的大小和形状进行改善。通过分析仿生机器鱼的波动方程得到尾鳍面积与推力的关系,从鱼尾形状、鱼尾弧口深度、鱼尾大小、鱼尾软硬度4个方面出发,依次采用solidworks设计了鱼尾形状,根据2种软硬度下不同形状的游动速度,得到最佳形状及软硬度,在此最佳形状的基础上改变弧口深度,并通过实体实验确定了最佳鱼尾大小方案。实验结果表明:机器鱼的游动性能受鱼尾形状、大小、软硬度等多个因素共同影响,使用较软材料的月牙形鱼尾对鱼游行较为有利。

Robot Fish Swimming Performance Improve Methods

To improve the robot fish propulsion speed and propulsive force, change the size and shape of robot fish tail. Through analyzing fluctuation equation of bionics robot fish, acquire the relation of tail acreage and propulsive force, based on tail shape, arc-shaped end depth, size and hardness-softness, use solidworks to design tail shape, according to different swimming speed of different shapes under 2 hardness-softness conditions, acquire optimal shape and hardness-softness. Based on the optimal shape, change arc-shaped end depth, determine optimal tail size according to experiment. The experiment results show that the swimming performance is influenced by tail shape, size, hardness-softness and so on, use crescent tail made by soft material is good for swimming.
