摘要：

A process dynamic model of surging in a modular self-wiping co-rotating twin screw extruder caused by superposed disturbances from feeders is developed. The changes of output flow rate with time (surging) are predicted for various time dependent input modes such as step function and sinusoidal function inputs into the hopper and other ports part way along the length of the machine.
