During the past five years that the USAMP/USCAR Light Metal Division has been studying aluminum structure casting it became obvious that a clear understanding of the most up-to-date solidification modeling technology was needed. Furthermore, the suitability of Kubo's model for USCAR's mule castings has been studied. To better understand state-of-the-art solidification modeling technology, commercially available software has been applied to an automotive suspension component, a lower control arm for a cadillac model. Together with conventional flow and solidification analyses, porosity formation simulation has also been demonstrated. The amount and location of predicted porosity are now well documented through experimental work and production castings. It is now possible to make accurate porosity predictions using Kubo's porosity model. The use of this algorithm on the USCAR/USAMP mule casting has confirmed porosity growth not before predicted by the conventional solidification analysis. The reduced porosity and improved mechanical characteristics in a redesigned USCAR's mule casting have therefore been confirmed.
