| 摘 要： | 为研究单螺杆榨油机在压榨过程中,榨膛内部油料与榨螺相互作用产生的流场分布及变化规律,建立了榨螺和流体域的物理模型。在Fluent软件中采用k-e模型及SIMPLEC求解器进行有限元仿真求解,获得油料在主压榨段的压力场和速度场分布,并通过流固耦合分析,得到榨螺受油料挤压发生的受力变形情况,以及榨螺在压榨过程中易发生较大变形和应力集中的位置。

| Abstract: | In order to study the flow field distribution and variation law of the interaction between oil and screw in the chamber of a single screw press, a physical model of the screw press and the fluid field was established. In Fluent software, k-e model and SIMPLEC solver are used to solve the finite element simulation. The distribution of pressure field and velocity field of oil in the main pressing section is obtained. Through fluid-structure coupling analysis, the stress and deformation of the screw under oil extrusion are obtained, and the location where the screw is prone to large deformation and stress concentration during the pressing process. |
