【Abstract】 The optimal design of convergent channel of extruder tubular head was discussed.The flow of polymer material in a convergence channel of tubular head was analyzed by applying the basic theory of a viscous fluid.A simplified mathematical model of the optimal design of convergence channel geometry parameters of tubular die was established according to the optimal target with the minimal energy consumption per unit output.This model was solved by means of complex method.Finally,the suggested convergent inner radius,convergent outside radius and convergent inner angle were determined.更多还原
