| 摘 要： | 建立了双螺杆挤出机轴向加热双通道机筒的有限元模型，分别对试压工况、正常工况和极限工况等条件下，双通道机筒的温度分布、应力分布和变形进行了有限元分析。本算例3种工况的热力耦合载荷作用下的有限元分析结果表明，轴向加热双通道机筒的设计合理，能够满足强度和加热需要。对机筒进行的有限元分析，不仅对机筒结构的强度进行了校核，也对加热通道的优化设计有所帮助。

| Abstract: | A finite element model is established for a twin-screw extruder barrel with two heating pipelines in the axial direction.The finite element analyses for three working conditions namely pressure test conditions,ambient conditions and critical conditions were completed in order to predict the distributions of temperature,stress and the deformation of the barrel.The calculated loads of the coupled thermal-force under the three working conditions show that the design of the twin-screw extruder barrel with two h... |
