摘　　要：以三段七区物理模型为基础 ,采用面向对象程序设计语言VisualC ++,对整个单螺杆挤出过程进行了数值模拟 ,所得压力、温度等工艺参数的模拟结果与实验值吻合较好 ,说明采用数学模型的正确性和数值算法的可行性。On the basis of the three stage and seven section model of the single screw extrusion,the numerical simulation for the whole extrusion process was realized by means of Object Oriented Programming Visual C++ The pressure and temperature distribution along the screw were also in good accordance with the experiments,proving the numerical simulation correct and numerical calculation feasible
