基于轨迹-传热耦合模型的温度场特性研究

Research on APS Temperature Field Characteristics Based on Different Robot Trajectory Patterns

以喷涂机器人工具中心点(Tool Center Point,TCP)及等离子热源中心点的位置一致性为结合点,利用FLUENT中的UDF模块加载TCP实时位置和等离子体射流以及高温粒子热源数学公式,构建了机器人运动轨迹与等离子喷涂过程传热行为之间的耦合模型,并通过仿真实验研究了特定机器人轨迹在基体表面形成的温度场分布情况。

On the basis of spatial-position consistency between the robot Tool Center Point（TCP）and APS heat source center point,this work aimed to develop a coupled model between robot motion and thermal behavior of APS process.The real-time TCP position and the thermal flux transferred by the plasma jet and sprayed particles were integrated in coupled CFD and FEM models by the UDF module of FLUENT.The temperature field distribution of substrate under specific robot trajectories was investigated through the simulation experiment.
