La Dynamique Du Rotor Dhlicoptre: Identification Des Charges Dynamiques Du Rotor Principal Dhlicoptre (Omn.Univ.Europ.) (Fre,Used
Delivery time: 8-12 business days (International)
Ltude du comportement dynamique des rotors des hlicoptres permettant de rsoudre divers problmes lis leurs fonctionnements. Lobjet principal de ces travaux de recherche est de mettre en uvre un modle permettant de simuler le comportement dynamique dun rotor vertical. Une tude de larodynamique des hlicoptres a t faite pour la dtermination des charges arodynamiques appliques sur le rotor principal de lhlicoptre. Ce qui a permis de dvelopper un modle dlments finis de la pale et den dduire leurs frquences et modes propres. Les calculs des diffrentes nergies et des travaux virtuels des diffrents lments du rotor ont t dvelopps. Un modle simple a t dfini afin dtudier les phnomnes vibratoires. Pour traiter des systmes rels, un modle dlments finis a t dvelopp. Ce modle permet dextraire les frquences propres et les dforms modales du rotor, et de calculer les contraintes agissant sur la structure pour les diffrents modes propres. Ltude des rotors en rgime transitoire permet de dterminer les rponses vibratoires dues aux balourds et aux diffrentes excitations.
