Les engrenages travaillent dans des conditions en g\u00e9n\u00e9ral s\u00e9v\u00e8res et par cons\u00e9quent ils sont soumis \u00e0 des d\u00e9t\u00e9riorations progressives de leurs \u00e9tats, notamment au niveau des dentures (usure, \u00e9caillage, fissure, rupture). Ces d\u00e9faillances peuvent alors limiter leur dur\u00e9e de vie.\u00a0 L\u2019\u00e9tude se porte sur la mod\u00e9lisation du comportement dynamique des engrenages \u00e0 deux degr\u00e9s de libert\u00e9 dans le cas sain et en pr\u00e9sence de d\u00e9faut local et distribu\u00e9. L\u2019analyse du comportement dynamique de l\u2019engrenage est r\u00e9alis\u00e9e dans le domaine temporel et fr\u00e9quentiel. La variation de la rigidit\u00e9 dans le temps est la principale source d’excitation dans le comportement dynamique des engrenages. La mod\u00e9lisation des d\u00e9fauts des dentures d\u2019engrenages est r\u00e9alis\u00e9e en utilisant des mod\u00e8les de rigidit\u00e9 de denture. Le comportement dynamique du\u00a0 syst\u00e8me d\u2019engrenage est d\u00e9crit par un syst\u00e8me diff\u00e9rentiel, r\u00e9solu par un sch\u00e9ma d\u2019int\u00e9gration de Newmark. Une \u00e9tude param\u00e9trique a \u00e9t\u00e9 r\u00e9alis\u00e9e sous Matlab pour l\u2019analyse de l\u2019effet des d\u00e9fauts d\u2019engrenages, le rapport de contact ainsi que l\u2019erreur de transmission dynamique. D\u2019apr\u00e8s les r\u00e9sultats obtenus on peut conclure que les d\u00e9fauts (local et distribu\u00e9) ont un tr\u00e8s grand effet sur le comportement dynamique de l\u2019engrenage.<\/p>\n
