摘　　要：[目的]为了研究受限管道对仿生机器鱼游动性能的影响,[方法]采用计算流体动力学(CFD)方法对机器鱼在受限管道环境中的自主游动性能进行数值模拟,对管道形状、靠壁距离和摆尾频率等参数对机器鱼自主游动性能的影响进行分析。[结果]结果表明:机器鱼靠近管道壁面游动会降低游动速度、推进力和游动效率,机器鱼在方形管道中的游动性能比在圆形管道中好,增大机器鱼的摆尾频率能提高推进力但会降低游动效率。[结论]研究结果可为管道检测机器鱼研发提供一定参考。[Purpose]In order to investigate the effect of restricted pipelines on the swimming performance of biomimetic robotic fish,[Method]Computational Fluid Dynamics(CFD)is used to numerically simulate the autonomous swimming performance of robotic fish in a restricted pipeline environment.The influence of parameters such as pipeline shape,wall distance,and tail swinging frequency on the autonomous swimming performance of robotic fish are analyzed.[Result]The results show that the movement of robotic fish near the wall of the pipeline can reduce swimming speed,propulsion force,and efficiency.The swimming performance of robotic fish in square pipelines is better than in circular pipelines.Increasing the frequency of robotic fish wagging can improve propulsion force but reduce swimming efficiency.[Conclusion]The research results can provide some references for the development of pipeline inspection machine fish.
