14. Summary of results#

The two models (Axisymmetric and \(\mathrm{3D}\)) pass without problems. The convergence is rapid. The results between modeling AXIS and 3D modeling are similar.

In the same way, methods CONTRAINTE and CONTINUE give equally satisfactory results. In this example, the CONTINUE method seems to converge more quickly than CONTRAINTE, especially in 3D with GLISSIERE.

For the particular case of sliding contact: modeling C is then taken as a reference. By method CONTINUE, solutions close to these reference values are obtained, with generally a lower number of iterations.

In the figure above we show the position of the pin for a displacement of the rear face of the piece of \(\mathrm{20,}\mathrm{70,}155\mathrm{mm}\).

This test made it possible to validate:

  • the « passage » of geometric singularities (acute and obtuse angles),

  • taking into account two contact zones (multi-zone contact),

  • the modeling of a slide-contact.
