摘　　要：通过流体分析软件ANSYS对塑料双螺杆挤出机的熔体输送段以及模口挤出段进行了流场模拟,做出了模口特性曲线、螺杆特性曲线和挤出机的有效工作图。利用该图可以讨论螺杆和模口的联合设计,丰富挤压理论,促进挤出理论的进一步发展,为双螺杆挤出机的设计,以及对现有设备的更有效利用提供理论依据和实践指导,该方法为研究开发工作节约大量的资金和能源,缩短了开发周期。By simulation of plastic melting stock delivery section and model orifice forced out section of double screw extruder, based on fluid analysis software ANASYS, the model orifice property curve, screw property curve and extruder work graph are worked out, by which the design of screw and model orifice can be discussed, which will enrich extrusion theory, promote further development of extrusion theory and provide theoretical base and practice direction for double screw extruder design and the present equipment. This method saves great number of funds and energy resources for research and development and shortens developing period.
