Développement d’une méthodologie d’essais appropriée à l'étude des phénomènes tribologiques liés à l'opération d'emboutissage
Development of a testing method for extended friction contact simulation in deep drawing
Laboratoire de Science et Génie des Surfaces, URA CNRS 1402, Ecole des Mines de Nancy
Abstract
Strip drawing is a technique often chosen to simulate frictional contact in deep drawing. We show that the flat/flat tool/sheet contact can be replaced favourably by line contact in cylinder/cylinder geometry provided that multipass operation is adapted in the latter case.
Identical apparent contact pressures and overall tool sliding distance on the sheet prove to be efficient similarity criteria.
Line contact multipass operation is especially suitable for detailed study of surface damage production during tool/sheet sliding contact.
