摘要
应用有限元分析软件ANSYS对同向旋转双螺杆挤出机螺纹输送元件中的三维非牛顿流动进行了模拟 ,计算出在一定转速和挤出量等工艺条件下螺纹元件的建压能力 ,确立了一定导程螺纹元件的特性曲线。在此基础上 ,对组合式同向旋转双螺杆挤出机工作特性进行了分析 。
Simulation of three dimensional non-Newtonian flow in screw element of corotating twin screw extruder was developed by using commercial finite element analysis software, ANSYS The pressure distributions under various screw speed and throughput were obtained, and the characteristic curves to describe the relationship between throughput and pressure gradient of the screw element were plotted Finally the analysis on work character of the modular corotating twin screw extruder was carried on, and the application of the characteristic curve of the screw element in calculating of the filled length and devolatilization length were discussed
