Method for predetermining clamping voltages to be applied to screw for fastening casings of gear box of automobile, involves estimating minimum clamping voltage to be applied to bonding zone based on estimated force
The method involves geometrically defining components (C1, C2) and a bonding zone (ZC) in a region of contact zones (ZT) of a pair of surfaces (S1, S2) of the components representative of a screw (V) by a three-dimensional model by finite elements. A contact property associated with each contact zon...

| description | The method involves geometrically defining components (C1, C2) and a bonding zone (ZC) in a region of contact zones (ZT) of a pair of surfaces (S1, S2) of the components representative of a screw (V) by a three-dimensional model by finite elements. A contact property associated with each contact zone is defined by biasing the components. Force exerted by the bonding zone is estimated based on the biasing and the contact property. A minimum clamping voltage to be applied to the bonding zone is estimated based on the estimated force. An independent claim is also included for a device for predetermining clamping voltages to be applied to a screw for fastening components.
Un procédé est destiné à prédéterminer des tensions de serrage à appliquer à au moins une vis (V) pour solidariser des composants (C1, C2). Ce procédé comporte une étape (i) consistant à définir géométriquement les composants (C1, C2) et au moins une zone de collage (ZC) voisine de zones de contact (ZT) d'une paire de surfaces (S1, S2) de ces derniers et représentative d'une vis (V), à définir chaque sollicitation subie par les composants, et à associer à chaque zone de contact (ZT) une propriété de contact, une étape (ii) consistant à estimer l'effort subi par chaque zone de collage (ZC) en présence de la sollicitation et des propriétés de contact des zones de contact (ZT) voisines, et une étape (iii) consistant à estimer la tension de serrage minimale à appliquer à chaque zone de collage (ZC) en présence de chaque effort estimé qu'elle subit. |
