| 中文摘要: |
| 研究了3 种有限元分析方法——流函数法、侧壁因子修正法和全高三棱柱单元法在挤出机平板机头流道分析中的应用情况。结果表明，流函数法只适合分析流道高度不变化或变化极小的情况；侧壁因子修正法误差较小；全高三棱柱单元法比较精确，但分析方法复杂。 |
| 英文摘要: |
| The flow channel in extruder sheeting-die is analyzed with 3 finite element methods，i.e.flow function method，sidewall factor correcting method and total height triangular column element method.The results show that the flow function method is only suitable for the flow channel with constant height or least-variable height；the smaller error is obtained with the sidew all factor correcting method；and the total height triangular column element method is more accurate，but the operation is complex. |
