摘　　要：针对典型的熔融沉积快速成型喷头结构,建立了喷头的热分析有限元模型,分析了喷头的热传递路径和过程,应用有限元软件ANSYS对喷头的温度场和应力场进行数值模拟仿真。结合仿真分析和实验研究,分析了喷头堵塞的原因并提出了解决方法,为喷头的温度控制和结构优化设计提供了参考。Based on the typical fused deposition modeling nozzle structure, a finite element thermal analysis model of the nozzle was established. Numerical simulation on temperature field and stress field of the nozzle was carried out by software ANSYS after analysis of the heat transfer path and process of the nozzle. Combined with simulation analysis and experimentation, the reasons of nozzle clogging were analyzed and the solutions were put forward. This paper provides reference for temperature control and structure optimization design of the nozzle.
