| 摘 要： | 用有限块法对高弹粘流在三维变厚度狭缝流道中的流动进行数值模拟.求出流体流量在流道中的分布规律;通过对实际板材挤出模鱼尾型流道中设置阻流块对流动影响的计算,证实有限块法是简易可行的,从而为挤出模的计算机辅助设计提供了一个重要手段.

| Abstract: | The distributive law of flow rate is studied for highly viscoelastic flow inthree-dimensional slit channel with varying thickness by using Finite Block Element Method(FBM).As an example,the influence of restrictive block on flowrate is obtained in fish channel of the plate extruding die and the results ofnumerical simulation are in concordance with the approximatical analytical solution.It is proved that FBM can be considered as an important tool for CAD/CAM. |
