RESUME<\/strong><\/p>\n

Ce travail s’adresse \u00e0 l’analyse par la m\u00e9thode des \u00e9l\u00e9ments finis (MEF) du m\u00e9canisme de d\u00e9gradation par fatigue de contact des roulements \u00e0 billes. Ceci se manifeste sous forme de ph\u00e9nom\u00e8ne d\u2019\u00e9caillage d\u00fb aux fortes charges appliqu\u00e9es.<\/em><\/p>\n

Une m\u00e9thode num\u00e9rique par \u00e9l\u00e9ments finis a \u00e9t\u00e9 utilis\u00e9e pour calculer la dur\u00e9e de vie en fatigue des roulements \u00e0 billes. Ces calculs pr\u00e9visionnels n\u00e9cessitent la connaissance des param\u00e8tres d\u2019endommagement occasionn\u00e9s par les sollicitations m\u00e9caniques et environnementales. L’\u00e9tude montre une coh\u00e9rence acceptable inf\u00e9rieure \u00e0 7% entre les r\u00e9sultats donn\u00e9s par la MEF et la formulation analytique d\u00e9velopp\u00e9e par Basquin. L’influence de la temp\u00e9rature, du coefficient de frottement, de la vitesse de rotation et de la charge appliqu\u00e9e sur la dur\u00e9e de vie des roulements \u00e0 billes est trait\u00e9e en utilisant l\u2019\u00e9quation de Basquin qui permet la pr\u00e9vision de la dur\u00e9e de vie des roulements \u00e0 billes. L\u2019indice de fiabilit\u00e9 est calcul\u00e9 et les param\u00e8tres d\u2019influence sont \u00e9tudi\u00e9s.<\/p>\n
