Research on the Correlation between Extrusion Parameters and Screw Failure Based on Fluent

The Fluent module in ANSYS finite element analysis software was used to simulate the rubber flow in the metering section of the single-screw extruder, and 8 different finite element models of screw and barrel gaps were designed to analyze screw wear failure and extrusion The correlation between the parameters. According to the simulation results, the wear of screw will cause the change of rubber pressure and temperature. The greater the amount of wear, the more obvious the changes of pressure and temperature. After a certain degree of wear, the changes of pressure and temperature tend to be flat. According to the simulation results, it is believed that the screw wear fault can be diagnosed by monitoring the changes of the pressure and temperature of the rubber compound in theory.
