摘　　要：设计并开发了一种等离子熔射成形过程的数值模拟系统.系统描述了从射流至基体的整个熔射成形过程以及各对象的状态和行为,并生成熔射成形过程的三维动画.在分析中同时考虑射流、熔射粒子、皮膜的影响因子对熔射结果的影响,找出部分主要工艺参数对熔射的影响规律.由等离子熔射铁片模拟所得到的计算结果与实验观测现象基本符合,表明了此系统用于系统地模拟和分析等离子熔射成形过程是可行的.A new designed system was adopted to simulate the plasma spray process systematically,presenting the states and behavior of objects in the process and three-dimensional computer animation of the whole process.In the analysis the effects produced by the influencing factors of plasma jet,particles and coating growth were all considered.The influential rule of operational parameters was attained.The results obtained by the simulation were in coincidence with those measured in experiment basically.Therefore it ...
