摘　　要：为了使真空挤出机的绞刀设计更加合理,缩短轴刀的设计周期,减少绞刀的改进设计成本,以JKY95-65/60型真空挤出机为实例,通过ANSYS有限元分析软件对真空挤出机的泥料流场模型进行构建和有限元分析,得出绞刀的扭转切应力、vonMises等效应力和变形云图,明确绞刀的缺陷及其产生原因,对绞刀形状进行改进设计,得到能够满足安全性施工要求的绞刀模型。In order to make the design of vacuum extruder reamer more reasonable, there is a need to shorten the design period of the axial knife, and to reduce the cost of reamer design for improvements. This paper, taking JKY95-65/60 type vacuum extruder as an example, constructs the mud flow field model of vacuum extruder and makes finite element analysis with the help of the ANSYS finite element analysis software, and gets the torsional shear stress reamer, von-Mises equivalent stress and deformation nephogram, makes clear the defects and the causes of the reamer, makes design to improve the shape of reamer, so as to get reamer model satisfying the safety construction requirements.
