摘　　要：本文采用热流固耦合的有限元分析方法,研究三种不同结构的挤出机熔体进料管中通入高黏熔体POE时,进料管所受到的压力场、速度场及热变形情况,通过数值对比,进而确定螺杆挤出机高黏熔体POE进料管的最优结构,同时将模拟值与实验值进行对比验证,发现误差在5%以内,该结构为后续挤出机连接结构方案的设计和优化提供了思路,同时降低设备能耗,提高设备产能。This article uses the finite element analysis method of thermal fluid solid coupling to study the pressure field,velocity field,and thermal deformation of the feeding tube of three different structures of extruder melt when high viscosity melt POE is introduced into the feeding tube.By numerical comparison,the optimal structure of the POE feed tube for high viscosity melt of the screw extruder can be determined.At the same time,the simulated values were compared and verified with the experimental values,and it was found that the error was within 5%.This structure provides ideas for the design and optimization of subsequent extruder connection structure schemes,while reducing equipment energy consumption and improving equipment production capacity.
