The mathematical models and program complex for synthesis of reciprocating extruders with adjustable configurations

The program complex which enables solving tasks of structural and parametrical synthesis of reciprocating extruders with adjustable configurations has been developed. The complex includes modules for extruder brand choice, assembly and visualization of 3D model of extruder screw, calculation of geometrical parameters of elements and sections of assembled screw configurations, synthesis of a mathematical model of extrusion, and calculation of its output parameters. The complex is configured to various types of polymeric films, as well as throughput and energy consumption requirements. The combined modeling method is implemented by the complex. It consists of synthesis of a static model for calculation of polymeric material state parameters, extruder throughput and energy consumption, indices of extrudate quality and a dynamic model for calculation of average residence time. Calculation results are visualized in the form of 3D graphs of criterion indices’ dependence on controlling influences. The complex is an effective tool for helping production personnel determine screw configurations and extruder regime parameters, ensuring required extrudate quality when performing restrictions for throughput and energy consumption for various types of films.
