摘　　要：针对一种需要在封闭、充满变压器油介质、空间狭窄、无照明的环境中完成异物检测及清理任务的变压器内部检查机器人,对其在潜油运动下的流场、热场等多物理场进行仿真分析,并对螺旋桨推力进行仿真计算,同时通过有限元方法计算螺旋桨旋转时产生的气泡体积。最后,计算机器人在油液中运动时的整体受力情况。仿真结果表明:变压器内部检查机器人在承受一定应力情况下仍能正常运行;同时推进器螺旋桨能提供足以使机器人本体正常运动的推力,且在旋转过程中生成的气泡不会影响变机器人的正常工作。Aiming at a transformer internal inspection robot that needs to complete foreign object detection and cleaning tasks in an environment that is closed,filled with transformer oil medium,narrow space,and without lighting,the flow field,thermal field and other multi-physics fields under the submersible oil movement were simulated and analyzed,and the propeller thrust was simulated and calculated,and the bubble volume generated when the propeller rotates was calculated by the finite element method.Finally,the overall force of the robot when it moved in the oil was calculated.The simulation results show that the transformer internal inspection robot can still operate normally under certain stress and collision conditions;at the same time,the thruster propeller can provide enough thrust to make the robot body move normally,and the bubbles generated during the rotation will not affect normal work of the robot.
