摘　　要：为实现仿生机器鱼靠壁游动的工程实际需求,研究了机器鱼靠壁游动过程的壁面效应特性.首先建立了机器鱼运动学模型,然后采用计算流体动力学方法对机器鱼靠壁游动过程的水动力学和流场分布进行了数值仿真计算,最后对机器鱼在不同靠壁距离下的水动力参数进行了实验测试分析.结果表明：固体壁面会对机器鱼靠壁游动过程的水动力参数产生影响,靠壁距离越小,产生的偏航力矩和侧向力越大,从而导致机器鱼形成远离壁面的偏航游动.To realize the near wall swimming of biomimetic robot fish for actual engineering requirements,the wall effects in robotic fish near wall swimming process was studied.Firstly,a kinematic model of robotic fish was established.Then,the hydrodynamics and flow field distribution in robot fish near wall swimming process was numerical simulated by use of computational fluid dynamics method.Finally,the hydrodynamic parameters of robotic fish under different near wall distance were tested and analyzed.Results show that the solid wall has an effect on the hydrodynamic parameters of robot fish in near wall swimming process.The smaller near wall distance,the larger yaw moment and lateral force are generated,leading to the yaw movement of the robotic fish.
