Thèse de doctorat
| Résumé : | Nowadays, the assembly of small (<1mm) components has become an industrial reality. Many domains like MEMS, surgery, telecommunications, car industry, etc. now have large use of micro-parts. At this scale, predominant forces are different than in macroworld. The pieces often undergo adhesion problems. The adhesion forces can be splitted in different components : van der Waals, electrostatics and capillary condensation. This work focuses on capillary condensation as it often can be the major component of the adhesion force. The first part of this work details a review of literature of different fields involved in capillary condensation. A simulation tool is then implemented and theoretically validated in the second part of the work. Finally, a test bed is presented; this bed is then used to experimentally validate the simulation results. Experiments and simulation results are shown to concord. Therefore, the simulation tool can be used to model the force due to capillary condensation. |
