An original hybrid gear model is introduced, which combines lumped parameter and finite elements along with a specific interface aimed at coupling mismatched discrete models. A mortar-based interface is presented, which eliminates the numerical errors induced by direct collocations between the tooth contact and gear body models. It is shown that the proposed interface can capture the instant contact conditions in the profile and lead directions for both spur and helical gears. A number of quasi-static and dynamic simulation results are presented, which illustrate the potential and practical interest of the methodology. It is observed that thin rims are more influential in the case of helical gears and that the overall dynamic tooth loads seem largely uncoupled from the local contact conditions on the teeth.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
