Abstract EN
The head runner of a rubber extruder is important for controlling rubber flow and improving extrudate quality.
To clarify the effect of the structure parameters of the head runner of a doubleplex tread extruder on extrudate quality and obtain high-quality rubber extrusions, a finite element model of the down head runner was established.
The extrusion process was analyzed through numerical simulations, wherein the Bird–Carreau constitutive equation and Navier slip law were used along with some computational methods, such as quadratic interpolation of velocity and linear interpolation of pressure and viscosity.
The Newton iteration algorithm was used for numerical calculations.
The mean-square deviation of velocity (SDV) of rubber flow in the outlet cross section was selected as the evaluation objective.
A Placket–Burman design was used to select three key factors—angles A and B and outlet width D—from among eight runner structure parameters affecting the velocity variance.
By using central composite design (CCD), the quadratic response surface model using the three key factors was established, and the influence law of a combination of the three key factors on SDV was obtained.
The response surface model was optimized using the simulated annealing (SA) algorithm, and the optimal key factors of the head runner were obtained.
The optimal runner design realizes a more uniform velocity distribution in the outlet cross section.
Furthermore, a comparison of the simulated flow velocities of the original and optimal head runners at different inlet flow ratios and temperatures indicates that the optimal head runner flow velocity improves the extrusion quality.
Thus, an optimal runner with optimal key factors was manufactured.
Test results of the rubber flow state indicated that the flow is regular and that warping disappears.
The proposed optimization strategy can be used practically for improving the head runner design, shortening the product development cycle, and reducing the production cost.
