External friction in the simulation of the screw extruder

Aret V.A., Verboloz E.I., Pelenko F.V., Pelenko V.V.

The problem of describing the process of extrusion with the use of an elasto-compressible model of dispersed medium and law of Coulomb- Amonton in the zone of the forcing of auger extruder with the specific assumptions is posed and solved. Is given an example of calculation with the aid of the personal computer and the batch of the mathematical programs of MathCAD with the specific values of the geometric and kinematic parameters.
