中文摘要:
      构建L型宽幅片材机头的三维物理模型,利用ANSYS WORKBEM、H和POLYFLOW软件对机头内部幂牢流体的压力场和速度场进行模拟。分析结果表明,当口模高度为4 mm、阻尼高度为3.5mm、主流道首末端直径比为1.2:l~l:1时,L型机头具有较好的挤出效果。
英文摘要:
      A threedimensional physical model for Ltype wide extrusion die was established,and the pressure field and velocity field of internal power-law fluid were simulated by ANSYS WORKBENCH and POLYFLOW software. The analysis results showed that,when the die height,damping height and the ratio of start diameter and end diameter of the mainstream channel were 4 mm,3.5 mm,l.2 :l~l:l,respectively,the extrusion result was good.
