DIE BALANCING: COUPLING FLOW SIMULATION, SHAPE DEFORMATION, OPTIMIZATION

摘要

The current work demonstrates a novel automatic approach for the die balancing process. The algorithm involves flow simulation through computational fluid dynamics (CFD) and shape change via automatic shape deformation (ASD) to minimize the flow non-uniformity at the die exit. Taking a spiral mandrel die as an example, the combined use of ASD with CFD is highlighted. Using this approach, one baseline simulation was manually set up and two more simulations were automatically created study the effects of helical angle. In the example studied, it was found that changing the helical angle from 315° to 405° had a minor effect on the flow uniformity.
