中文摘要：

以TCMD125A型真空练泥机变螺距、变槽深连续螺旋绞刀部分为研究对象,建立了泥料在绞刀中挤出的几何模型,并进行数值模拟。分析了陶瓷泥料在挤出过程中的运动机理,对泥料挤出过程中速度、压力分布情况作了详细的分析。

英文摘要：

Based on the part of the variable pitch, variable groove depth continuous screw of the model TCMD125A de-airing pug mill, establish the extrusive geometric model of paste in screw, and make numerical simulation of it. Analyse the movement mechanism of ceramic paste during the process of extrusion, detailed analyse the velocity, pressure distribution.
