摘　　要：运用Solidworks三维建模软件建立喂料段沟槽衬套的实体模型。利用ANSYS/FLUENT进行有限元流场分析,针对单螺杆挤出机制备再生胶时喂料段螺旋沟槽衬套的沟槽深度,沟槽宽度,沟槽个数对胶料固体输送速率的影响进行了分析。本文还对挤出机喂料段沟螺旋槽衬套的沟槽深度,沟槽宽度及沟槽个数等参数进行了优化。其研究结果对单螺杆挤出机制备再生胶时喂料段沟槽衬套的设计及参数选取有一定的指导意义。Solidworks 3D modeling software is used to establish a solid model of the feeding section groove liner,and ANSYS/FLUENT is used for finite element flow field analysis.This article analyzes the effects of groove depth,groove width,and number of grooves on the solid conveying rate of the rubber material during the preparation of recycled rubber using a single screw extruder.This article also optimized parameters such as groove depth, groove width, and number of grooves for the spiral groove liner in the feeding section of the extruder. The research results have certain guiding significance for the design and parameter selection of the feeding section groove liner in the preparation of recycled rubber by single screw extruder.
