采用基于ANSYS 的有限元法,分析了不同黏度的物料在变截面管中的流动速度分布,不同变截面数的软塑管对出口段物料流速的影响,以及不同管径比和不同管长比的变截面管中的物料流动速度分布。找出了控制残留量的主要因素和技术参数,以此对现存的软塑包装管提出了一些改良措施,为设计新的低物料残留的软塑包装管提供分析数据支持。

Flow velocity distribution of materials with different viscosity in variable cross section tube was analyzed based on ANSYS. The influence of number of variable cross sections on material flow velocity of exit section was analyzed. The main factors and technical parameters to control residue quantity were founded and determined. Improvements on present plastic tube packaging were put forward. The purpose was to provide technical support to design new packaging of low residue.
