A Study on Rotating Compression Forming of Ring Based on the Upper Bound Method

Abstract:

In this paper, an upper bound approach of rotating compression forming of ring is established. Using the upper bound approach, the effects of friction factor, reduction, aspect ratio etc upon compression force, radius of neutral surface, internal radius, spiral lead etc are investigated systematically. The experiment of rotating compression forming of ring made of aluminum alloy A6061 was carried out. Comparisons between the analytical results and the experiment are used to verify the validity of present upper bound approach. The analytical results are in good agreement with the experiment.
