摘　　要：应用专业的网格划分软件ICEMCFD构造水下运动仿真模型并划分网格，应用计算流体力学软件Fluent对水下运动进行压力场求解。计算中．建立profi1e文件边界网格的运动，采用SIMPLE算法和标准κ-ε湍流模型。得出了水下运动的压力场分布和受力曲线．为水下机器人动力学分析提供准备。Exoskeleton robot underwater environment operation, control difficulty increased sharply. In order to realize the precise control of underwater robot, must go for underwater robot dynamics analysis and obtain the control parameters of the model .For underwater power robot dynamics analysis, relative to others diffi- culty lies in the underwater exoskeleton robot force is nonlinear variation, there are many factors that can affect stress, using the experimental model is difficult to give a good indication of force analysis. This arti- cle according to the human body model gb, apply the ICEM-CFD to build a simulation model and meshing, set up a profile based on the variation of freestyle knee joint Angle ,make boundary of the human body model to move. Use the fluent software to realize the simulation and obtain force of the human body model in the water.
